Omschrijving

Are you looking for a senior backend engineer to build, improve, or troubleshoot a reliable software system?

I specialize in backend development with Python, Django, FastAPI, and C#/.NET. I can help you develop REST APIs, modernize existing applications, integrate external services, improve database performance, and solve production or deployment issues.

I have hands-on experience with PostgreSQL, Redis, Celery, Docker, Kubernetes, AWS, Google Cloud, CI/CD pipelines, and high-availability systems. My focus is not only on writing code, but also on creating maintainable, scalable, and production-ready solutions.

I can support you with:

Backend and API development
Django and FastAPI applications

C#/.NET backend services
Database and performance optimization
Cloud infrastructure and deployments
Technical reviews and architectural improvements
Debugging complex production issues

I am particularly interested in clearly scoped projects, technical audits, integrations, and part-time backend assignments. I communicate clearly, work independently, and focus on delivering practical results.
