    Buffered, Eventually - Youtube System Design

    Buffered, Eventually is a system design podcast where two senior engineers break down how large-scale video platforms like YouTube are built—and the tradeoffs behind every layer. We discuss video upload pipelines, transcoding, storage, CDN delivery, feed and search indexing, recommendations, and view counting at scale. Each episode focuses on real-world constraints: latency vs quality, cost vs reliability, and consistency in systems that serve billions of hours of video. No hype, no buzzwords—just practical conversations about designing massive media systems.

    Indexed, Eventually

    Indexed, Eventually is a system design podcast where two senior engineers break down how large-scale post search systems are built—and where they break first. Using a Facebook-style post search as a running example, we dive into inverted indexes, write-heavy ingestion, ranking by likes vs recency, caching strategies, and the tradeoffs between freshness, cost, and performance. We talk through real constraints: high write volume, massive storage, hot vs cold data, and why “just sort at query time” never works. No buzzwords—just practical design decisions and honest tradeoffs.

    At Scale: Messaging System

    A system design podcast where two senior engineers break down how messaging platforms like WhatsApp are built at scale—and the tradeoffs behind every architectural choice. We discuss core problems such as real-time messaging, message delivery guarantees, end-to-end encryption, scalability, latency, storage, and reliability. Each episode focuses on why certain decisions are made, what alternatives exist, and what you gain or lose with each approach. The conversations are practical and experience-driven—no fluff, no theory dumps. Just clear explanations of complex systems, real-world constraints, and the design tradeoffs that matter in production. If you want to understand how large-scale messaging systems work under the hood, this podcast is for you.
