I’m Adam Kuzniarski. TypeScript full-stack and mobile developer,
father and husband.

I build production-ready web and mobile applications with React, Next.js, Expo / React Native, and NestJS.

My background combines hands-on software development with strong ownership, communication, and operational experience from team leadership and process-driven roles. I enjoy building practical products, designing clean APIs, and solving real-world problems with pragmatic software.

My focus is on TypeScript across frontend, backend, and mobile, with a strong interest in full-stack web apps, mobile apps, and backend systems that are structured, reliable, and useful in everyday life.

In parallel, I’m expanding my backend skill set through hands-on Java and Spring Boot projects. Languages: Polish (native), German (native), English (B2). Based in Offenbach am Main and open to roles in the Rhine-Main area or remote.

Tech Stack

My core stack is TypeScript-first full-stack development with React, Next.js, NestJS, PostgreSQL, Prisma, Tailwind CSS, and Docker.
