- Python and TypeScript product engineering
- Reliable deployment, documentation, and operational support
A local document assistant built with FastAPI, Streamlit, Ollama, ChromaDB, and SQLite. It keeps files, embeddings, conversations, and model requests on the host machine while providing workspace-isolated retrieval and inspectable source citations.
Engineering signals: automated tests, static typing, offline RAG evaluation, migrations, Docker, CI, security documentation, and fictional sample documents.
A security-clean reconstruction of my 2024 Computer Engineering final-year prototype. It combines modular WisBlock sensing, RAK4631 firmware, LoRaWAN telemetry, exact 13/15-byte payload compatibility, cross-language decoders, compiled firmware checks, and a sanitized public case study. It is documented honestly as an academic prototype—not a certified life-safety system.
A Next.js and Supabase payment-flow demonstration with an isolated local demo mode, Binance Pay order signing, payment-status tracking, and an administration view. Production-sensitive actions are separated from mock behavior and documented explicitly.
A scheduled Python market scanner that ranks volume and price-action setups, applies explicit risk assumptions, limits duplicate alerts, and sends qualified results to Telegram.
I currently lead enterprise AI strategy, governance, agent development, and automation at Pnyx Hill, while serving as Senior IT Specialist at Globaltraining / University of Nicosia.
My operational scope includes support for 200+ staff and platform users, Microsoft 365 administration, device lifecycle management, onboarding and offboarding, MFA and access controls, asset tracking, knowledge documentation, and learning platforms. I also build frontend, IoT, and AI systems on a freelance basis.
My earlier work includes technical support, account administration, networking, hardware repair and diagnostics, web platforms, and end-user training.
