Corneliu Croitoru · AI Architect & Product Builder

20+ years of shipping software. Since 2023, everything I build is GenAI-based.

I design and build GenAI systems: agents, LLM pipelines, evaluation. Today as Staff GenAI Solutions Architect at Betclic, leading GenAI architecture and MCP adoption. Before that, 7 years at AWS: cloud architect for hundreds of customers, serverless and edge, then 30+ prototypes built with customers.

What I love is the whole product, not just the AI: the idea, the architecture, the UX. Two of mine are live, and I co-founded both: StreetLens and Back From My Trip.

And I photograph the places I travel to.

Photography

Photography is my other passion. I shoot the places I travel to. For years that meant a Canon, APS-C then full frame, and later a Sony mirrorless. Now it's mostly my iPhone: the best camera is the one you always have with you, and the Pro models have been really good these last few years.
