Jan Jetze Beitler

I'm a software developer and DevOps engineer based in Wormer, the Netherlands. I design, develop, and maintain cloud-based software systems with a focus on reliability, maintainability, and scalability. I prefer automation over manual processes and value clean code, reproducibility, and pragmatic solutions over complexity.

Day to day I work across the full stack — from backend services in Go and Python to AWS cloud infrastructure and CI/CD pipelines. I'm particularly interested in serverless architecture, infrastructure as code, and developer productivity tooling. AI-assisted development has become a core part of my workflow — I use GitHub Copilot at work and Claude Code for personal projects. It has fundamentally changed how I build software, and I'm always looking for new ways to integrate AI into my development process.

Before moving into software development, I completed a Master's in Data Science at the University of Amsterdam. My thesis research resulted in PIE: Pseudo-Invertible Encoder, a paper co-authored with Ivan Sosnovik and Arnold Smeulders and submitted to ICLR 2019. That academic background gave me a strong foundation in problem-solving and analytical thinking that I apply every day in my engineering work.

Outside of tech, some people may know me from a brief stint making music — I wrote a couple of Dutch protest songs against the student loan system that got some attention back in the day. That chapter is behind me, but the videos are still on YouTube.
