About Me

From Idea
to Production

Fullstack developer with 3 years of professional experience. At Gizmeon I work on an ad exchange platform end to end — React and TypeScript on the frontend, Node.js and NestJS services on GCP behind it — including real-time data pipelines, reporting dashboards, and a PWA media player.

Outside work I run two products of my own, Everframes and MyHireLoop, and volunteer as a backend developer at two German startups, including CXR AI in Worms. Based in Mannheim, Germany with work authorization (Chancenkarte). English C1, German A2 and improving.

Off the Clock

Hobbies

Hiking — The Mountain Guy

Most weekends I'm somewhere in the Bavarian Alps, walking uphill on purpose. I keep a hand-drawn memory book of the trails — Eibsee, Partnachklam, Gaisalpsee and Seealpsee so far — photos, maps and all.

Photography

One overworked camera roll — mostly lakes, ridges and night skies from the trips above.

Building Side Projects

Everframes, MyHireLoop, and whatever comes next — small products I design, build and run end to end.
