"you ain't never gon' be happy 'till you love yours" — J. Cole
ML engineer, ECE student at NTUA, pre-national karate athlete. I'm 19 and based in Athens. I work on sovereign AI infrastructure at a fast-moving startup — the kind of work that's shaping what European AI looks like. I'm drawn to the hard problems: the ones that sit at the edge of what's understood and what's possible. I build to understand. I compete to stay sharp. I'm here for the long game.
Part of a small team building the full production stack for Sophea AI — Greece's first sovereign large language model. Work spans model training on NVIDIA DGX B200, voice stack integration (ASR/TTS), and multimodal capabilities. The model serves regulatory document analysis, accounting automation, and enterprise customer support.

AI & IT Intern
Athens, Greece
Jul – Sep 2025
Collaborated on the architectural design and prompt engineering of Aktor's first internal AI Agent. Optimized enterprise reporting pipelines by structuring large-scale SAP ERP datasets via complex SQL queries — bridging AI tooling with legacy enterprise infrastructure.

A controlled study of catastrophic forgetting in small language models. Trained a 17M parameter GPT from scratch on 1B tokens of standard English, then fine-tuned it on Gen Z slang across eight data regimes — measuring WikiText-103 perplexity and style shift at every step. Key finding: perplexity increases 47x after just 1k tokens of fine-tuning, while style acquisition plateaus at 18–20% regardless of data volume.

AI Karate Analysis System
2025 · In Progress
Computer vision system for objective biomechanical scoring of karate technique. Built a 30+ FPS real-time skeleton tracking engine using OpenCV and MediaPipe, applying vector calculus for precise kinematic analysis — velocity, Center of Mass trajectory, angular momentum.
Scalar-valued autograd engine and neural network library from scratch in C++. Implements dynamic computational graphs, low-level memory management, and full forward/backward passes without any external ML dependencies. The foundation of all subsequent deep learning work.
