System Design Mastery

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 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.

Feed Meets Telemetry is a system design podcast where two senior engineers break down how fitness platforms like Strava are built—and the tradeoffs behind every design choice.

We talk about activity tracking, GPS ingestion, real-time sync, feed generation, leaderboards, data accuracy, and scalability.

No hype, no buzzwords—just clear conversations about designing large-scale fitness and activity systems.

Nearest cab is a system design podcast where two senior engineers break down how ride-hailing platforms like Uber are built—and the tradeoffs behind every decision.

We discuss real-time matching, geo-indexing, dispatch algorithms, pricing, reliability, and scalability under extreme load. Each episode focuses on practical design choices, constraints, and failure scenarios drawn from real production systems.

No hype, no theory dumps—just clear conversations about building large-scale, real-time systems.

Verified Review is a system design podcast where two senior engineers break down how local business review platforms are built—and the tradeoffs behind every design choice.

The conversations are practical and experience-driven, focusing on real-world constraints rather than idealized solutions. No buzzwords, no hype—just clear explanations of complex systems and the tradeoffs engineers make when building review platforms used by millions.

If you want to understand how reputation and review systems work under the hood, this podcast is for you.

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.

The Scroll is a system design podcast where two senior engineers break down how real-world systems are built—and the tradeoffs behind every decision. From news-feed architectures and recommendation systems to scalability, performance, and reliability, we talk through what actually works in production and why.

If you’re an engineer who enjoys understanding how systems really work, this podcast is for you.

That price-drop alert didn’t come from vibes.
This episode explains how price tracking systems like CamelCamelCamel work — from crawling and deduping product data to alerting users at scale — in a chill, no-textbook system design walkthrough.

That feed refresh is doing a lot of work.
This episode breaks down how Instagram’s system design handles uploads, timelines, likes, and massive traffic — explained in a chill, no-textbook way.

That comment flying up the screen didn’t just magically appear.
This episode explains how Facebook Live-style comment systems work — handling real-time writes, massive fanout, and ordering — all without killing latency.
