URL Shortener

URL shorteners like bit.ly and tinyurl.com appear simple but involve complex system design challenges including distributed ID generation, caching strategies, and handling massive read/write ratios at scale.

Rate Limiter

Rate limiters are critical components that control the flow of requests to protect systems from overload and ensure fair resource allocation. This episode explores design patterns, algorithms, and real-world implementations used by major tech companies.

About the Show

AI-generated, interview-focused system design discussions

Byte by Design is a system design podcast where two AI hosts geek out over distributed systems, scalability challenges, and the engineering decisions behind products used by billions of people.

Each episode is fully generated by a Python pipeline: research, script writing with humor and personality, a three-agent quality review panel, multi-voice audio synthesis, and architecture diagram generation — all automated end to end.

Topics range from classic interview problems (URL shorteners, chat systems) to modern infrastructure (LLM serving, vector databases, serverless platforms). Every episode references real engineering blogs from companies like Google, Netflix, Stripe, and Uber.

Episode Format

Every episode follows five structured segments.

  • 🎯 The Problem Why this system is interesting and harder than it looks.
  • 📋 Interview Framework Requirements, estimation, and the architecture sketch.
  • 🔬 Deep Dive The hard parts — scaling, trade-offs, what actually breaks.
  • 🏭 How They Built It Real companies, real architecture, real war stories.
  • 💡 Interview Tips What impresses interviewers and common pitfalls.
