    "Thanks to Ilya and his team I am now in a position to take my AI driven SaaS platform to market here in the US. Ilya led the work as the AI solutions architect and AI developer, taking ownership of the overall architecture and delivery. He helped implement the core product on a React + AWS stack, including a solid data/auth foundation and clean integrations for our AI layer (LLM + RAG). As a founder Ilya was exactly the kind of engineering partner I was looking for. Highly recommend Ilya."
