Message

At Cosmos Business Systems, I develop frontend features with React, TypeScript and JavaScript. I build reusable UI components with DevExtreme and integrate REST APIs into responsive interfaces.

At Promotion ADV, I designed and developed websites and WooCommerce stores, customized WordPress themes and Elementor layouts, and handled deployment and maintenance.

My background also includes IT support and business software implementation at KosmosTech. For my diploma thesis at Technical University of Crete (TUC), I built a smart-home experimental platform using Home Assistant and developed Python tools for experimentation and data analysis.
