EXPERIENCE ACROSS
ABOUT ME
Practical by nature.
Curious by default.
My career has moved between keeping systems working and understanding the information those systems produce.
I started in hands-on IT infrastructure and telecom billing operations, then worked with analytics platforms, enterprise migrations, process governance, and IT/OT operations in Germany. That mix helps me look at a problem from both the technical and business sides.
Outside my day-to-day work, I build and operate independent projects, from public-data dashboards to a live AI-assisted job application product. I enjoy turning an idea into something people can actually use.
