🎓 Senior AI Engineer | AI Consultant | Agentic AI & RAG Specialist
📍 Athens, Greece | Open to Full-Time & Freelance/Contract Work
I'm a Senior AI Engineer with 9+ years building and shipping production software systems — from research prototypes to enterprise-scale deployments. I specialize in Agentic AI (LangGraph), Retrieval-Augmented Generation (RAG) pipelines on Azure AI Search, and MLOps, working across Healthcare, Cybersecurity, and Banking domains.
Currently, I'm Senior ML Engineer, AI Consultant & Software Developer at Grant Thornton, leading enterprise AI transformation for Greece's Independent Authority for Public Revenue (IAPR), and Senior Software Engineering Consultant at EETAA, driving government modernization through enterprise-scale systems migration. I've also led AI transformation efforts for the National Bank of Greece as an Enterprise AI Banking Solutions Architect.
Over my career I've delivered 50+ AI projects, contributed to 10+ EU-funded research initiatives (Horizon Europe, Horizon 2020, FP7), and remain deeply passionate about applying AI and Data Science responsibly for meaningful, real-world impact.
