Thread 01 — Web Development

The full stack,
end to end.

Performant, accessible web applications — from pixel-precise interfaces to scalable backends. I ship production software with Next.js, TypeScript, and modern tooling.

How I write code

Clean, typed, and built to scale.

Code other developers enjoy working with. Strong typing, server actions for mutations, and a clear separation of concerns — defaults, not afterthoughts.

  • TypeScript-first, end to end
  • Component-driven architecture
  • Server rendering by default
  • Optimistic UI for mutations
  • WCAG-compliant, keyboard-first
  • Edge-ready deployments
