About

Software Engineer who builds and ships production AI and full-stack systems end to end.

I design and maintain a live fintech platform — payments, Greek tax-authority e-invoicing, automated data collectors and an in-house AI assistant — across backend (Python, Django, FastAPI, Celery), frontend (Next.js, React) and cloud (Heroku, AWS). Hands-on with the modern LLM stack: tool calling, Retrieval-Augmented Generation, embeddings and vector search. Open to AI/LLM, full-stack or backend roles building real products.
