About Me

I'm a Senior Full Stack Developer based in Athens, Greece, with 5+ years of experience building production-grade web applications. I started as a backend developer and gradually expanded into full stack — today I design and ship entire SaaS platforms, from database architecture and REST APIs to React frontends and Docker deployments. I've worked on high-traffic retail systems, multi-tenant B2B platforms, and I've built Eukairon — a multi-tenant SaaS booking platform — from scratch using Laravel, React, MySQL, Docker, and Stripe. I care about clean code, solid tests, and shipping features that actually solve business problems.
