    Edge Computing for Robotics: The OrbCare Case Study

    I made a decision that saved me six months and probably $200,000: I put the AI on the device, not in the cloud. In this episode, I walk through the architecture of OrbCare—a HIPAA-compliant health monitoring robot I'm building—and show you exactly why edge-first architecture isn't just technically superior for hardware startups, it's the only approach that actually works at scale. What you'll learn: The mental model shift from cloud-centric to edge-centric thinking (this changes everything)Why "what needs to happen locally?" beats "what's the minimum to send to cloud?"Real technical decisions: NVIDIA Jetson Orin Nano, YOLO, MediaPipe, encrypted local storageHow edge-first architecture makes HIPAA compliance easier, not harder (video never leaves the device)The trade-offs nobody talks about: hardware constraints, updates, debugging, cost structureEdge vs. Cloud decision framework you can use todayThe case study: All AI inference on-device (object detection, pose estimation, breathing analysis)20-30 FPS processing with 50ms latencyWorks during internet outages (designed for disconnection, not connection)Near-zero cloud costs per devicePrivacy by default—no PHI transmissionWhy this matters: Most hardware startups default to cloud-first because that's what they know from web development. Then they hit Series B and realize they need to rebuild everything. That's $2-5M and 12-18 months you don't get back. This is the architectural decision that determines whether you scale smoothly or spend 18 months on a rewrite when you should be growing revenue. For founders building robotics, medical devices, IoT, or edge AI—this episode shows you how to avoid that wall.

    The 7 Red Flags I Look For in Hardware Startup Architectures

    $20 million Series B. Six months into production. Total architecture rebuild required. This happens more often than you think. And it's completely avoidable. In this episode, I walk through the 7 architecture red flags I've learned to spot immediately when reviewing hardware startup systems: Security as "Phase 2" (why this destroys hardware companies)Cloud-first thinking for edge devices (your robot shouldn't be a brick when WiFi drops)No fail-safe architecture (things break - have a plan)Real-time requirements as an afterthought (milliseconds matter)Ignoring the firmware update problem (you can't update your update system if it's broken)Underestimating data pipeline complexity (that arrow on your diagram is hiding chaos)No hardware-software testing strategy (manual bench testing doesn't scale)PLUS: Big announcement - this podcast is now "Before the Rewrite" and I'm bringing VCs onto the show to talk about what they actually look for in technical due diligence. We're creating frameworks you can use to assess your architecture against what investors evaluate. For hardware founders building robotics, medical devices, or AI at the edge - this is architecture guidance before it becomes a fundraising obstacle.

    The Data Integrity Death Spiral - How Fast-Moving AI and Robotics Companies Accidentally Build Compliance Nightmares

    Think compliance slows you down? Think again. This week, Peter Ferreira breaks down why brilliant AI and robotics teams keep accidentally building $8 million compliance nightmares – and how to avoid becoming one of them. You'll discover why "we'll add compliance later" is the new "we'll add the foundation after building the house," plus the three architecture pillars that let you move fast AND stay bulletproof when regulators come knocking. Whether you're building autonomous systems, ML pipelines, or any AI-powered product heading for enterprise customers, this episode will save you from rebuilding your entire data architecture when compliance requirements hit. Key Topics: Why data lineage should be a core capability, not an afterthoughtThe "immutable everything" approach that doesn't kill performanceHow to automate compliance instead of drowning in manual processesReal architecture patterns that scale with regulations instead of fighting themAction Items: Audit your system's traceability gaps this weekTest if you can replay any decision from 3 months agoRedesign with compliance as a constraint, not a bolt-onPerfect for CTOs, engineering leaders, and founders who want to build systems that work for users AND auditors.

    Build vs Buy in Biotech - Making Smart Technology Decisions When Lives Depend On It

    Ever been in a meeting where someone casually suggests "Oh, we'll just build our own LIMS" and you're thinking "Do you have ANY idea what you just said?" This episode is for you. Peter Ferreira breaks down the million-dollar question every biotech company faces: when to build custom solutions versus when to just buy existing tools and focus on the science that actually matters. Through the cautionary tale of Sarah's $3M custom LIMS disaster (spoiler: her competitor beat her to market by 18 months using off-the-shelf software), you'll learn a practical framework for making build-vs-buy decisions that could save your company millions and keep you focused on breakthrough discoveries instead of debugging barcode scanners. Whether you're a biotech CTO trying to balance innovation with compliance, a founder wondering if you should build your own clinical trial platform, or a technical leader tired of reinventing wheels while competitors race ahead, this episode gives you the strategic clarity to make smart technology decisions when lives depend on it. What You'll Learn: The "Is This Actually Our Superpower?" framework for build-vs-buy decisionsWhy regulatory compliance changes everything (and why your weekend dashboard won't cut it)Real cost breakdowns that include the hidden expenses everyone forgetsHow to integrate commercial platforms with your proprietary scienceThe one question that cuts through all the noise and saves you from expensive mistakesNo jargon, no BS, just practical advice from someone who's seen biotech companies succeed and fail based on these exact decisions. #Biotech #CTO #TechnicalDueDiligence #BuildVsBuy #LIMS #Startups #BiotechCTO #TechStrategy #RegulatoryCompliance #LifeSciences #SoftwareDecisions #TechLeadership #DrugDevelopment #BiotechFounders #FDA #GxP #ClinicalTrials #LabTech #BiotechPodcast #TechManagement #Innovation #21CFRPart11 #BioPharma #MedTech #TechInvestment #ProductStrategy #EngineeringManagement #BiotechEntrepreneur #TechStack

    Technical Debt: When to Care and When to Ignore

    A founder just spent $500K and six months "cleaning up code" that worked perfectly fine. His competitors ate his lunch while he was organizing digital filing cabinets. Technical debt sounds scary, but here's the truth: most of it doesn't matter. In this episode, we're demystifying the most misunderstood concept in startup tech and showing you when to fix, when to ignore, and when to stop letting perfectionist developers derail your business. You'll discover: Why David's $500K "code spa retreat" was expensive procrastinationThe "Is This Actually a Problem?" system for technical debt triageHow to fix real issues without killing your development momentumThe 70-20-10 rule that keeps you shipping while improving your systemsWhy your authentication system from 2019 is probably just fine (seriously)Perfect for: Founders being pressured to "fix technical debt," CEOs wondering if they should halt feature development for refactoring, and entrepreneurs who want to make smart technical decisions without the engineering drama. Key insight: Fix the problems that hurt your business, not the problems that hurt your developers' feelings. Part of our scaling series: Building on our episodes about startup failures, flexible tech architecture, and strategic hiring. #TechnicalDebt #TechStrategy #StartupTech #FounderAdvice #TechDecisions #CodeQuality #TechManagement #StartupMistakes #DeveloperProductivity #TechPriorities #BusinessStrategy #StartupGrowth #TechLeadership #SoftwareDevelopment #TechDebtManagement
