Founder of YaliKit. Builds developer tools full-time and ships every tool you see on the site. Previously worked on data platforms at scale. Writes about JSON, CSV, regex, performance, and the small details that make browser tools feel native.
Beyond formatting and validation: how to structure JSON for readability, performance, and forward compatibility. Real patterns from production codebases, the anti-patterns that bite at scale, and what to do about timestamps, IDs, optional fields, and schema evolution.
A complete tour of building a polished browser game with Three.js, Web Audio synth sounds, and HTTP-polling multiplayer rooms. The geometry choices for rock/paper/scissors pads, the performance budget on retina screens, why we skipped WebSockets, and the room-code architecture designed for a future tournament hub.
