Notes from running the React Compiler on the BetterDocs admin (a 4-year-old codebase with ~80 components and useMemo scattered everywhere) and starting clean with it on xCloud v1. What broke, what did not, and where I still reach for manual memoization.

Notes from rebuilding sapan.dev with the View Transitions API for navigation across 16 locales. Replaced an entire Framer Motion orchestration layer with a CSS file, found one annoying flash on RTL Arabic, and walked away with a much smaller bundle.

PerformanceEdge Computing for Frontend Developers
On sapan.dev the locale-detection logic lives at Vercel Edge — sub-30ms response from anywhere on the planet. On TubeOnAI we used Cloudflare Workers for auth-token validation. Notes on what genuinely belongs at the edge and what I have learned the hard way to keep regional.
