Tristan Manchester

I'm Tristan.

Software Engineer and Data Scientist based in Munich. I build tools for science, native apps, websites, and other things I find interesting.

PhD in Materials Science, two years at Diamond Light Source, the UK's national synchrotron, building instrumentation and deep-learning tools for scientific imaging.

Available for freelance contracts in Munich and remote. Let's talk.

Research Background

Before commercial software, I built novel imaging tools at Diamond Light Source — the UK's national synchrotron — developing ML pipelines and JAX-based reconstruction algorithms for high-resolution X-ray tomography.
