About Me

I'm an AI Engineer and Freelancer specializing in turning AI ideas into reliable, scalable systems that deliver real business value. Many AI projects fail because they remain prototypes — I specialize in making them production-ready.

My expertise spans Generative AI, RAG pipelines, and AI Agents. I build systems that automate workflows, power knowledge systems, and integrate seamlessly into existing products.
