EU citizen, open to roles in Germany, Greece & Switzerland (remote-friendly) and to freelance projects.

I’m a frontend engineer from Greece, based in Berlin. For three years at KPS AG I shipped production e-commerce frontends for German retail brands (Dehner, NORMA, Jungheinrich and EP:) across SAP Commerce Cloud, Spryker, Magnolia and Storybook, with accessibility and performance as a constant discipline.

These days I build AI systems on top of that frontend foundation, not instead of it. PawGuard is a civic-tech app I’m building with four custom Claude Code subagents, each bound by a written constitution; Lead Finder is an LLM analyzer pipeline; Aegeon, Ego Distillers, Kryotera and the T.E. Learning Center are live sites I shipped solo.
