Web · Mobile · Backend

I build complete digital products. From web to mobile to backend, I handle everything so you don't need a massive team.

I help founders and product owners launch scalable digital products by acting as a one-person technical team handling Next.js web apps, React Native mobile apps, and robust backend APIs.
