About

The Engineer Behind the Build

I'm a full-stack developer from Xanthi, Greece, now based in Kalamaria. My work spans headless architectures, custom WordPress and WooCommerce plugins in PHP, and decoupled React / TypeScript / Vite frontends — not just themes and templates, but engineered systems built for scale.

Beyond the web, I'm a STEM instructor and IoT researcher pioneering smart agriculture solutions. I'm currently building MCP servers and custom AI agent skills that automate development workflows, reporting, compliance, and content pipelines — bridging traditional engineering with the agentic future.
