My personal Proxmox VE cluster, built and broken and rebuilt more times than I can count. It hosts a CRM with Telegram briefings, a photo archive (Immich), a Minecraft server, and an AI agent pipeline, all wired together over LXC networking and Tailscale for remote access. Most of what I know about networking and system architecture came from debugging this thing at 2am — DNS resolution issues, container routing, storage quirks, all of it.

This is my first real AI project, and I'm learning a lot of it on the job. I'm working on the backend for a conversational health assistant built jointly by American College of Thessaloniki and Aristotle University, handling patient-facing dialogue in a cardiology context. Still very much figuring out prompt design, retrieval, and how to keep the output safe — happy to talk through what I've learned so far.

A course project where I trained a small neural network (an MLP) to guess whether a word was Croatian, Greek, Turkish, Russian, or German, based on the NorthEuraLex dataset. I didn't know much about NLP going in — this was mostly trial, error, and reading a lot of documentation. Landed at 95.6% accuracy, which felt like a small miracle at the time.

This site. Rebuilt from scratch for Voxxed Days Thessaloniki 2026. Fast, no unnecessary framework bloat, no dead code — just the stuff I actually needed.

Working on the backend for a patient-facing cardiology assistant — prompt design, retrieval, evaluation, and safety guardrails. My first professional AI role, learning a lot of it as I go.
