Back to original languageAbout Robin
I am a Senior Fullstack Product Engineer and I help companies reliably bring complex B2B products into production.
My focus is on fullstack SaaS and data-intensive systems where frontend UX, backend logic, and architecture must work together cleanly. I particularly enjoy working on products with multiple user roles, real-time processes, or demanding data flows.
In projects, I take responsibility beyond just the code: from technical conception and implementation to maintainability and scalability. I place great value on clear structures, understandable solutions, and close collaboration with product and business stakeholders.
Technologically, I primarily work with React & TypeScript on the frontend and Python, Go, and PostgreSQL on the backend – always with the goal of building robust and usable products, rather than short-term workarounds.
