About Me

The Short Version

I'm a Computer Science graduate from Greece, currently based in Kraków, Poland. My passion is artificial intelligence — specifically building practical AI tools that solve real business problems.

I spent 6+ years working at major multinationals like Accenture, Infosys, and HEINEKEN, where I gained deep understanding of how large enterprises operate — the processes, the pain points, and the communication dynamics that make or break projects.

That corporate experience gave me something most AI builders don't have: I know what the actual problems look like from the inside. Now I'm combining that real-world understanding with hands-on AI development — building RAG systems, chatbots, and automation tools inspired by the problems I've seen firsthand.

AI Tools I'm Building

Each project demonstrates a different aspect of modern AI engineering — from retrieval-augmented generation to document intelligence and agentic workflows.

These tools are inspired by real inefficiencies I encountered during my 6+ years in enterprise finance operations — manual processes, slow decisions, and inconsistent data handling that are exactly the kind of problems AI can solve.
