Simon Poppinga

Senior Software Developer & Architect

I build scalable .NET architectures, distributed cloud systems, and accessible modern web applications.

About

I'm a software developer with around ten years of experience in .NET and modern web frontends — from embedded software operating in moving vehicles to distributed cloud systems scaling on Kubernetes.

I work in a structured, goal-oriented manner backed by strong analytical problem-solving skills. I adapt quickly to new concepts and languages, placing great value on clean code and collaborative teamwork. Whether serving as Technical Lead or collaborating in agile product teams, I focus on building reliable, well-architected systems.

I actively use AI as an everyday engineering accelerator and have deep practical experience integrating AI capabilities into customer enterprise solutions.
