Background

Software engineer (M.Sc.). I build reliable systems, 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.
  • Talos: local-first workspace operator for governed developer tasks.
  • True-Rolls: ChaCha-based verifiable rolls with signed receipts.

Art's paramour
