Background

Software engineer (M.Sc.). I create, reliable systems with: Java/Spring services and local-first tools for LLMs. Comfortable in ambiguity, allergic to heroics, big on documentation.

What I value

  • ClaritySimple interfaces, explicit contracts.
  • IntegrityTests, transparency, reproducibility.
  • MomentumSmall PRs, daily progress, steady releases.
  • RespectCode reviews that teach, docs that de-stress.

Recent work

  • Large-scale HCM SaaS: features + cross-regional fixes.
  • LOQ-J: local-first RAG CLI (Lucene vectors + Ollama).
  • True-Rolls: ChaCha-based verifiable rolls with signed receipts.

Art's paramour

Moved by music, image, and story, with a lifelong commitment to the craft. I play, I learn, I feel it in my chest, and I let it change me.
