Vissarion Zounarakis

I'm Vissarion (call me Aris!) a Barcelona-based software engineer originally from Greece. I'm building plain, reliable software and tools you can trust.

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.
