About

Engineering with purpose

I'm an AI Architect. Language-agnostic and goal-focused — I pick the right tool for the job, not the other way around. Over the years I've designed and shipped AI-powered platforms, LLM integrations, and production ML pipelines for startups and enterprises alike.


I care about outcomes over technology choices, clean system design, and infrastructure that scales. When I'm not building AI systems, I maintain open source projects and explore the frontiers of generative AI, agent architectures, and cloud-native ML tooling.
