I build AI features that make it into production — retrieval pipelines, prompts, and the backend services that keep them honest. Lately that means LLM assistants on Azure at Accenture; before that, enterprise software at Chubb and TeamViewer.

// 01 about
I'm a Senior AI Engineer at Accenture in Greece. Most of my week goes into an LLM-powered conversational assistant for a large enterprise client: retrieval over Azure AI Search and CosmosDB, prompt design, and the FastAPI services that put the whole thing in front of real users.
My background is plain software engineering first — Python, Java and .NET, plus databases, automated testing and DevOps. That shows in how I work: I care more about whether an AI feature is reliable and maintainable than about whether it demos well.
Before AI I worked in enterprise environments at Chubb and TeamViewer, and I hold an MEng in Computer Science & Engineering from the University of Ioannina. Outside work I keep tinkering — compilers, simulations, small tools. This site is one of them.
