About

Software architect and senior engineer. I build practical, no-fluff resources for engineers leveling up — starting with a system design interview cheat sheet, more career and interview prep tools on the way. Always happy to talk shop on system design, career growth, or what you're building.

Cheat sheet for system design interviews - A repeatable framework for system design interviews

A 16-page cheat sheet built for senior/staff software engineers: a 5-step answer framework, capacity estimation numbers, and 10 fill-in-the-blank playbooks for the questions that come up again and again — URL shorteners, rate limiters, chat systems, and more.
