About
I build AI products, not just AI demos.
My focus is turning AI capabilities into reliable software people can actually use. I work across the complete AI application stack, from model APIs and embeddings to backend systems, automation, interfaces, and production deployment.
Whether it is a knowledge assistant, document processing system, business automation, or an AI SaaS platform, I focus on creating practical solutions with measurable value.
