AI engineer in Karlsruhe, Germany. I build internal AI tools end to end—RAG assistants, Teams bots, and the pipelines behind them.
Now. Working student at Mercedes-Benz Tech Innovation, researching sandboxing and isolation for AI agents that run unattended.
Before. Sole AI developer at RÜKO GmbH Baumaschinen, where I built a RAG assistant, a Teams equipment bot, and the document pipeline behind both. Earlier, NLP and automation at EnBW.

Projects
Five things I have built: a production system for a construction-machinery fleet, and four open-source tools.
RAG assistant & Teams bot
Production RAG assistant in daily use by ~50 staff, and a Teams bot answering equipment questions across a fleet of 2,395 construction machines: SQL inventory lookups, manual search, advisory answers. Built both as sole AI developer, plus the shared document-ingestion pipeline.
WinMux
tmux-style tiling terminal for Windows that runs a fleet of parallel Claude Code sessions in one window, on real ConPTY shells. Open source, in daily use.
Ember
Desktop widget that reads local Claude Code and Codex logs for live plan headroom, session burn, and true API-equivalent cost.
StudyOS
Turns one sentence about a student’s courses into a populated semester workspace: planner, assignment board, reading list.
Harshal’s Hand Font
TrueType font drawn from my own handwriting.
