W10 Tech — a small design & build studio.
W10 Tech partners with founders and teams that want their web, app, or AI-powered product built with care. We take discovery, design, and engineering seriously — and we ship.
Most engagements start with a scoped build, then turn into a longer partnership. We work with small teams where it matters who writes the code.

Turborepo → Vercel: Production Lessons (Prisma, Caching, the .next Trap)

TypeScript 7 Is Here: The Go-Native Compiler (Project Corsa) in Practice
TypeScript 7.0 replaces the compiler with a from-scratch Go port — same types, roughly 10x the speed. Here is what actually changes in your editor and CI, and how to try it without rewriting anything.

Bun.sql and the Full-Stack Runtime: Do You Still Need a Postgres Client?
Bun ships a built-in Postgres client and a zero-config full-stack dev server. Here is what Bun.sql actually does, how it compares to postgres.js and Drizzle, and when the batteries-included runtime is enough.
A decade of shipping.
I've been writing production software for ten years — consumer healthcare at Everyday Health, AI-powered fitness products, and everything in between. I run W10 Tech because I like working directly with the people a product is for.
On the engineering side: TypeScript, React, Next.js, and Python are the tools I reach for. On the studio side: whatever lets us ship something that lasts.
