Senior Full-Stack Engineer · AI Solutions Architect · Technical Architect

📍 Athens, Greece | 🇬🇷 Greek / 🇬🇧 English

I'm a senior full-stack engineer with 15 years of experience architecting enterprise-scale systems for regulated industries. Currently the principal technical architect at the Greek Atomic Energy Commission (EEAE), where I've built national regulatory compliance platforms serving 1,200+ users and processing 50,000+ annual transactions.

I specialize in the intersection of full-stack engineering and applied AI — building systems that don't just work, but think.
