Philipp Niestroj

I build software that goes into production — from database structure to the last UI detail.

After several years as Head of Technology for a software company, where I was architecturally responsible for enterprise projects, I will be available as a freelancer from August 2026. My focus: independent development with real technical ambition.

Stack: Node.js (NestJS) · Vue 3 · Nuxt 3 · TypeScript · C# · PostgreSQL · MongoDB · React Native · Docker

I cover the full cycle: API conception, database design, frontend implementation, deployment. In addition, experience with the integration of LLM systems as a productive application layer — language processing, data extraction, API connections.
