About

I am an experienced full-stack developer with a focus on modern JavaScript stacks. I primarily work with React, Next.js, Vite, Redux, Node.js, Express.js, and TypeScript. On the database side, I am very familiar with both MongoDB and PostgreSQL. Remote work is standard for me, and I value structured, independent work and good collaboration. I coordinate closely with teams and partners across Germany over extended periods.\n\nI enjoy close collaboration with cross-functional teams and am comfortable operating in complex production environments, ensuring robust APIs, performance, and maintainable code.
