Work

Working student at Arteus Energy in Karlsruhe. I support growth and project management for battery energy storage systems (BESS). It's my first month and I'm learning a lot about the pipeline side of things after spending almost two years on the grid connection side at Terra One.

Study

Third semester of Industrial Engineering & Management at KIT. Still figuring out what I want to specialize in. Running with KIT Run a few times a week and doing Judo when my schedule allows it.

Community

Co-leading the YFN Karlsruhe chapter. We're organizing more events this semester and trying to connect with other student initiatives. The network has over 1,800 members now across the DACH region.

Still running Eisbaden Karlsruhe — weekly cold plunges in local rivers and lakes. The community has grown 3x since I started it in November 2024. We swim year-round.

Building

Tinkering with side projects when I find the time. Currently interested in vibe coding — building things fast, shipping early, iterating. Recently built Ersti-Hilfe and Swimma.
