    React Native at Scale with Kadi Kraman, Software Developer at Expo | Mobile Development, EAS, OTA Updates

    What does it actually take to build production React Native apps in 2026, and where does Expo fit in? In this episode of Señors at Scale, Dan sits down with Kadi Kraman, software developer at Expo, who has spent over six years in the React Native ecosystem, wearing every hat from IC to director. Kadi shares the story of how she went from writing C++ in a maths degree to becoming one of the early React Native engineers at Formidable, and eventually joining Expo to work on the platform itself. We dig into what makes React Native genuinely competitive with native iOS and Android development today, why Expo Go is now just for prototyping, how EAS workflows and fingerprint-based repacks dramatically speed up CI, the real story on OTA updates (and where the legal gray area sits), and what's still missing from the ecosystem. Kadi also gives a rare look at the new Expo agent for vibe-coding mobile apps, the case for React Native brownfield, and her honest take on Lynx as competition. Key Topics: - Why React Native + Expo is faster than native Xcode/Android Studio workflows - The mental shift from web to native (display points, gestures, pixel density) - Expo Go vs development builds, and why the recommendation has changed - EAS workflows, repack jobs, and project fingerprints - React Native performance, list rendering, and the React Compiler - OTA updates: when to use them, when not to, and what the stores actually allow - Debugging strategies (expo-doctor, native logs, AI-assisted log analysis) - Brownfield React Native and embedding RN screens into existing native apps - Lynx, competition, and the future of cross-platform mobile - Career advice on imposter syndrome, applying anyway, and finding talk topics GUEST: Kadi Kraman, Software Developer at Expo 💼 LinkedIn: https://www.linkedin.com/in/kadikraman/ 🐦 Twitter/X: https://x.com/kadikraman 🐙 GitHub: https://github.com/kadikraman 🌐 Website: https://kadikraman.com/ FOLLOW & SUBSCRIBE 🎙️ Podcast: https://neciudan.dev/senors-at-scale 📩 Newsletter: https://neciudan.dev/subscribe 💼 LinkedIn (Show): https://www.linkedin.com/company/senors-scale/ 💼 LinkedIn (Dan): https://www.linkedin.com/in/neciudan 📸 Instagram (Show): https://www.instagram.com/senorsatscale/ 📸 Instagram (Dan): https://www.instagram.com/neciudev ADDITIONAL RESOURCES - Expo: https://expo.dev/ - Kadi's "From Web to Native with React" blog post: https://expo.dev/blog - EAS Workflows: https://docs.expo.dev/eas-workflows/get-started/ - Expo Doctor: https://docs.expo.dev/more/expo-cli/#expo-doctor - Expo Fetch (streaming support): https://docs.expo.dev/versions/latest/sdk/expo/ #ReactNative #Expo #MobileDevelopment #JavaScript #iOS #Android #EAS #ExpoRouter #SoftwareEngineering #SeñorsAtScale 💬 What's your biggest pain point building React Native apps today, and have EAS workflows changed your CI setup?

    AI at Scale with Nico Martin from Hugging Face | Transformers.js, Tokenizers, On-Device Inference

    Can you really run state-of-the-art machine learning models directly in the browser, with no server, no API calls, and full privacy by default? In this episode, Nico Martin, Open Source Machine Learning Engineer at Hugging Face and Google Developer Expert in AI and Web Technologies, walks through how Transformers.js makes on-device AI a reality. Nico's journey is anything but conventional. He started as a ski and windsurf instructor, taught himself web development on the side, spent years as a freelancer (including five at a bank building e-banking front ends), and recently landed what he calls his dream job at Hugging Face. We unpack what Hugging Face actually is (the GitHub for machine learning), how Transformers.js brings the Python Transformers API to the browser, and the real engineering challenges of running models on whatever hardware your users happen to have. Nico explains quantization, ONNX as the standard for portable model architectures, the role of tokenizers, how text becomes tensors, and why WebGPU matters for running larger models client-side. We also dig into the bigger picture: privacy-preserving AI, the difference between open weights and truly open source models, agents and MCP, and what front-end developers should actually learn to stay relevant in an AI-first world. Key Topics: - What Hugging Face is and the role of the Hub, Transformers, and Diffusers - Transformers.js: bringing Python Transformers API to JavaScript and the browser - The biggest challenge of browser ML: running on unknown client hardware - Quantization explained (Q4, 4-bit vs 16/32-bit) and how it compresses models - ONNX and ONNX Runtime Web: the standard for portable model architectures - Open weights vs open source models and why the distinction matters - Tokenizers, token IDs, and why each model needs its own tokenizer - From text to tensors: pre-processing, inference, and post-processing - Text embeddings explained through a simple animal feature analogy - WebGPU and what it unlocks for in-browser inference - Agents, tool calling, MCP, and how context windows get consumed - Advice for developers who want to break into AI and ML engineering 🔗 FOLLOW NICO 💼 LinkedIn: https://www.linkedin.com/in/nicodotdev/ 🐦 X/Twitter: https://twitter.com/nic_o_martin 🦋 Bluesky: https://bsky.app/profile/nico.dev 🐙 GitHub: https://github.com/nico-martin 🌐 Website: https://nico.dev 🎙️ FOLLOW & SUBSCRIBE 📸 Instagram: https://www.instagram.com/senorsatscale/ 📸 Instagram: https://www.instagram.com/neciudev 🎙 Podcast URL: https://neciudan.dev/senors-at-scale 📬 Newsletter: https://neciudan.dev/subscribe 💼 LinkedIn: https://www.linkedin.com/in/neciudan 💼 LinkedIn: https://www.linkedin.com/company/senors-scale/ 📚 ADDITIONAL RESOURCES - Transformers.js: https://huggingface.co/docs/transformers.js - Hugging Face: https://huggingface.co - ONNX: https://onnx.ai - ONNX Runtime: https://onnxruntime.ai - WebGPU: https://www.w3.org/TR/webgpu/ - Utopia for Realists by Rutger Bregman #MachineLearning #AI #HuggingFace #TransformersJS #WebML #OnDeviceAI #WebGPU #ONNX #JavaScript #Frontend #WebDev #SenorsAtScale #OpenSource 💬 Would you trust on-device AI over cloud-based models for sensitive data?

    Scaling Frontend at Perk with Giorgio Polvara | Monolith to Microfrontends, Vite, Zod

    What does it actually take to scale a frontend from 15 people in a converted flat to a 1,800-person unicorn, and then migrate the whole thing to microfrontends without breaking anyone's week? In this episode, Dan sits down with Giorgio Polvara, Staff Engineer at Perk (formerly TravelPerk) and the original creator of @testing-library/user-event (1M+ weekly npm downloads). Giorgio joined TravelPerk as employee #15, set up the frontend foundations that still power the product today, left to try engineering management at Toptal, realized he missed building, and came back as Staff. They get into the microfrontend migration that replaced a monolithic React app with vertically-split single-page apps served at the infrastructure layer, the rebrand that changed the name, domain, logo, and colors simultaneously, and the philosophy that ties it all together: you're not building features, you're improving a system that happens to produce features. Key Topics: - Scaling a frontend team from 7 engineers to a full platform tribe - Why 20% refactoring time is the wrong model - Monolith to microfrontends: SingleSPA vs the vertical-split architecture they built - Managing shared dependencies with pnpm, Syncpack, and Vite plugin packages - Contract testing with Pact vs runtime schema validation with Zod - Rebranding an entire product behind a feature flag, without leaking the design - Why Giorgio tried engineering management and went back to IC - Staff engineer advice: propose five solutions, expect one to land 🔗 FOLLOW GIORGIO 💼 LinkedIn: https://www.linkedin.com/in/polvara 🐙 GitHub: https://github.com/Gpx 🌐 npm: https://www.npmjs.com/package/@testing-library/user-event 🎙️ FOLLOW & SUBSCRIBE 📸 Instagram: https://www.instagram.com/senorsatscale/ 📸 Instagram: https://www.instagram.com/neciudev 🎙 Podcast URL: https://neciudan.dev/senors-at-scale 📬 Newsletter: https://neciudan.dev/subscribe 💼 LinkedIn: https://www.linkedin.com/in/neciudan 💼 LinkedIn: https://www.linkedin.com/company/senors-scale/ 📚 ADDITIONAL RESOURCES - A Philosophy of Software Design by John Ousterhout - Out of the Tar Pit (Moseley & Marks) - No Silver Bullet (Fred Brooks) - @testing-library/user-event: https://www.npmjs.com/package/@testing-library/user-event - SingleSPA: https://single-spa.js.org - Vite: https://vitejs.dev - Pact (contract testing): https://pact.io - Zod: https://zod.dev #staffengineer #microfrontends #frontendarchitecture #perk #travelperk #reactjs #softwarearchitecture #engineeringleadership #devtools #softwaredesign #senorsatscale 💬 How does your team handle the tension between shipping features and keeping the system healthy?

    Federated Systems at Scale with Zephyr Cloud | Module Federation, Edge Deploys, Reverse Tree Shaking

    How do you deploy federated front ends to the edge in 150 milliseconds? In this episode, Zack Chapple, CEO and Co-founder of Zephyr Cloud, and Nestor Lopez, Platform Engineer at Zephyr Cloud, break down everything developers need to know about micro frontends, module federation, and deploying at global scale without the infrastructure pain. Zack's journey started at a consulting company working with enterprises like SAP to add module federation support to Angular, which eventually revealed all the pain points of scaling federated architectures. That led to Medusa, then to Zephyr Cloud, the platform he describes as "Kubernetes for the front end." Nestor's path started eight years ago with Sencha.js and iframes, long before module federation existed, and brought him to Zephyr through open source contributions to TRPC and other projects. We cover why module federation is "Docker for the front end," how Zephyr deploys with one line of code and no CI/CD pipeline, their reverse tree shaking technique that recomposes federated bundles into a monolith at the edge, how Nestor deployed 5,200+ micro frontends as a single video, their federated MCP server for enterprise AI orchestration, and a TC39 proposal to fix ESM module unloading in V8. We also talk about pricing, open source contributions, and what it's really like to build a startup with four kids. Whether you're an enterprise team trying to ship frontend independently across dozens of teams, or a solo developer who just wants to deploy without setting up a CI/CD pipeline, this conversation covers the full spectrum. Key Topics: - Micro frontends explained through the microservices and Kubernetes analogy - Module federation as "Docker for the front end" and Zephyr as the orchestration layer - End-to-end walkthrough: from bundler to global edge deploy in ~150ms - No repo required, Zephyr hooks into any bundler and deploys on build - Reverse tree shaking: monolith performance with micro frontend dev experience - The Chrome extension for hot-swapping MFEs in any environment - Federated MCP servers built on module federation for enterprise AI - TC39 proposal to fix ESM module unloading and enable live HMR on Node.js - Bring your own cloud: Cloudflare, AWS, Fastly - Pricing: free for solo, $19/seat for teams, org-wide for enterprise - Mobile support through Metro and desktop through Tauri - Open source contributions and financially supporting projects like RSPack, SWC, and Tailwind 🔗 FOLLOW ZACK 💼 LinkedIn: https://www.linkedin.com/in/zackarychapple/ 🐦 X/Twitter: https://x.com/Zackary_Chapple 🐙 GitHub: https://github.com/zackarychapple 🔗 FOLLOW NESTOR 💼 LinkedIn: https://www.linkedin.com/in/nstlopez/ 🐦 X/Twitter: https://x.com/nstlopez 🌐 Blog: https://nstlopez.com 🎙️ FOLLOW & SUBSCRIBE 📸 Instagram: https://www.instagram.com/senorsatscale/ 📸 Instagram: https://www.instagram.com/neciudev 🎙 Podcast URL: https://neciudan.dev/senors-at-scale 📬 Newsletter: https://neciudan.dev/subscribe 💼 LinkedIn: https://www.linkedin.com/in/neciudan 💼 LinkedIn: https://www.linkedin.com/company/senors-scale/ 📚 ADDITIONAL RESOURCES - Zephyr Cloud: https://zephyr-cloud.io - Module Federation: https://module-federation.io - RSPack: https://rspack.dev - Hono: https://hono.dev - shadcn/ui: https://ui.shadcn.com #MicroFrontends #ModuleFederation #ZephyrCloud #Frontend #WebDev #PlatformEngineering #DevEx #EdgeComputing #Kubernetes #SenorsAtScale #OpenSource #Startup 💬 What's the most painful deployment workflow you've ever had to deal with?

    ServiceMesh at Scale with William Morgan, creator of Linkerd

    William Morgan is the CEO of Buoyant and the creator of Linkerd, the world's first service mesh and a CNCF graduated project powering production Kubernetes infrastructure at thousands of companies. Before founding Buoyant, William spent nearly four years at Twitter as a software engineer and engineering manager, where he shipped core platform features like the Twitter photo service and embed timelines — and watched the legendary monolith-to-microservices transformation unfold firsthand. In this episode, we cover what it was like engineering at Twitter during the fail whale era, how decomposing a monolith introduces entirely new networking challenges, why William invented the term "service mesh," and how Linkerd gives platform teams reliability, security, and observability without developers having to think about it. Whether you're a platform engineer running Kubernetes in production, an SRE trying to make sense of service-to-service communication, or a developer curious about what infrastructure teams actually do — this conversation is packed with hard-won lessons from a decade of building critical open source infrastructure. 🔸 Key Topics: - Engineering at Twitter in 2010: the Rails monolith, Scala rewrite, and microservices transformation - How replacing function calls with network calls changes everything - What a service mesh is and why the term had to be invented - Control plane vs data plane architecture - Why Linkerd rewrote its proxy from Scala/JVM to Rust - Latency-aware load balancing, mTLS, and protocol detection - Multi-cluster communication and mesh expansion to VMs - Common service mesh implementation mistakes - Linkerd vs Istio: William's honest take - Open source sustainability and enterprise monetization - The enterprise sales journey from engineer to CEO - Book recommendations: Hyperion, Gideon the Ninth, The Book of the New Sun 🔗 FOLLOW WILLIAM 💼 LinkedIn: https://www.linkedin.com/in/wmorgan/ 🐦 X/Twitter: https://x.com/wm 🌐 Buoyant: https://buoyant.io 🎙️ FOLLOW & SUBSCRIBE 📸 Instagram: https://www.instagram.com/senorsatscale/ 📸 Instagram: https://www.instagram.com/neciudev 🎙 Podcast URL: https://neciudan.dev/senors-at-scale 📬 Newsletter: https://neciudan.dev/subscribe 💼 LinkedIn: https://www.linkedin.com/in/neciudan 💼 LinkedIn: https://www.linkedin.com/company/señors-scale/ 📚 ADDITIONAL RESOURCES - Linkerd: https://linkerd.io - Buoyant: https://buoyant.io - Linkerd Getting Started: https://docs.buoyant.io - Linkerd GitHub (Proxy): https://github.com/linkerd/linkerd2-proxy - Hyperion by Dan Simmons - Gideon the Ninth by Tamsyn Muir - The Book of the New Sun by Gene Wolfe - Simon Willison's Blog (AI/LLMs): https://simonwillison.net #Linkerd #ServiceMesh #Kubernetes #Rust #CloudNative #Buoyant #CNCF #Microservices #Infrastructure #PlatformEngineering #SoftwareEngineering #SenorsAtScale 💬 What's the most complex networking issue you've debugged in a microservices environment?

    Databases at Scale with Tyler Benfield (Staff Engineer @ Prisma) | ORMs, Indexes, Connection Pooling & Scaling Postgres to Billions of Requests

    You can never build anything faster than your slowest database query. In this episode, Tyler Benfield, Staff Software Engineer at Prisma, breaks down everything developers need to know about database performance, from why your queries are slow to how Prisma scales Postgres to handle billions of requests on bare metal infrastructure. Tyler's path into databases started at Penske Racing, writing trackside software for NASCAR pit stops, and eventually led him deep into query optimization, connection pooling, and building Prisma Postgres from the ground up. We cover the most common ORM anti-patterns, why indexes are the single biggest performance lever most developers ignore, how Prisma Accelerate turns database connections into HTTP calls, and why Tyler thinks the SQL query language itself is fundamentally broken for modern web apps. Whether you're a frontend developer afraid to touch the database or a backend engineer scaling past your first million users, this conversation is packed with practical, immediately actionable advice. 🔸 Key Topics: - ORMs vs raw SQL vs query builders and when to use each - The most common Prisma anti-patterns that tank your app performance - How database indexes actually work (the address book analogy) - Connection pooling, serverless runtimes, and the problem Prisma Accelerate solves - Scaling Postgres on bare metal with memory snapshots and scale-to-zero - Per-query pricing and why Prisma charges differently than other providers - NoSQL vs SQL and when Postgres can handle both - Why SQL is a bad query language for nested relational data - The future of AI agents and databases, MCP servers, and ephemeral environments 🔗 FOLLOW TYLER 💼 LinkedIn: https://www.linkedin.com/in/tylerbenfield/ 🐦 X/Twitter: https://x.com/rtbenfield 🦋 Bluesky: https://bsky.app/profile/rtbenfield.dev 🌐 Website: https://tylerbenfield.me 🎙️ FOLLOW & SUBSCRIBE 📸 Instagram: https://www.instagram.com/senorsatscale/ 📸 Instagram: https://www.instagram.com/neciudev 🎙 Podcast URL: https://neciudan.dev/senors-at-scale 📬 Newsletter: https://neciudan.dev/subscribe 💼 LinkedIn: https://www.linkedin.com/in/neciudan 💼 LinkedIn: https://www.linkedin.com/company/señors-scale/ 📚 ADDITIONAL RESOURCES - Prisma ORM: https://www.prisma.io - Prisma Postgres: https://www.prisma.io/postgres - The Design of Everyday Things by Don Norman - The Design of Future Things by Don Norman - Designing Data-Intensive Applications by Martin Kleppmann - Aaron Francis (database education): https://aaronfrancis.com #Prisma #Postgres #DatabasePerformance #ORM #TypeScript #ServerlessDatabase #ConnectionPooling #SQLOptimization #WebDevelopment #SoftwareEngineering #FullStack #DatabaseIndexes #SenorsAtScale 💬 What's the worst database performance issue you've ever debugged?

    Open Source at Scale with Corbin Crutchley (TanStack Form & VP of Engineering)

    TanStack Form gets over a million downloads per week. Corbin Crutchley is the person behind it. But this conversation goes way beyond forms and frameworks. Corbin started coding professionally at 16, worked minimum wage at a charter school, taught himself Angular through sheer persistence, and eventually became a GitHub Star, Microsoft MVP, author of The Framework Field Guide, and VP of Engineering at Immersive Homes. Along the way, he built one of the most beloved open source form libraries in the JavaScript ecosystem and founded Playful Programming, a nonprofit that teaches people how to code for free. In this episode, we get into the real stuff: how he joined TanStack through a 30-minute conversation with Tanner Lindsley that turned into an invitation to lead a project, what it actually feels like to maintain a library that millions of projects depend on, why he almost quit open source after a wave of rude issues, and how he thinks about versioning as a social contract with your users. We also talk about framework agnostic architecture, why he wrote a free book that teaches React, Angular and Vue at the same time, the open source funding problem, and his transition from IC to VP of Engineering at Immersive Homes (which started with a game of Magic: The Gathering). He closes with something deeply personal about mental health in tech that I think everyone needs to hear. 📚 RESOURCES MENTIONED - TanStack Form: https://tanstack.com/form - TanStack: https://tanstack.com - The Framework Field Guide: https://playfulprogramming.com/collections/framework-field-guide - Playful Programming: https://playfulprogramming.com - Diataxis Documentation Framework: https://diataxis.fr - Will Larson's Books (An Elegant Puzzle, Staff Engineer): https://lethain.com - Engineering Management for the Rest of Us by Sarah Drasner - Shoe Dog by Phil Knight 🔗 FOLLOW CORBIN - GitHub: https://github.com/crutchcorn - LinkedIn: https://www.linkedin.com/in/corbincrutchley - Bluesky: https://bsky.app/profile/crutchcorn.dev - Twitch: https://twitch.tv/crutchcorn 🎙️ FOLLOW & SUBSCRIBE 📸 Podcast Instagram: https://www.instagram.com/senorsatscale📸 Dan's Instagram: https://www.instagram.com/nicudan📰 Newsletter: https://senorsatscale.substack.com💼 Dan's LinkedIn: https://www.linkedin.com/in/nicudan🌐 Website: https://neciudan.dev #SoftwareEngineering #OpenSource #TanStack #TanStackForm #JavaScript #TypeScript #ReactJS #Angular #Vue #FrameworkAgnostic #GitHubStar #VPofEngineering #EngineeringLeadership #TechLeadership #MentalHealthInTech #WebDevelopment #SenorsAtScale
