Aris Zounarakis

I’m Aris Zounarakis, a Barcelona based software engineer at ADP. I work on global HCM and payroll systems, mostly across full stack product and platform tooling. Outside work, it is tinkering, music, side projects, and a cold one. If you like it here, cheers!

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

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.
