Engineer-founder who owns the entire lifecycle: strategy → architecture → code → deployment → growth. I don't hand off — I ship.
Two things I can point at. I founded a marketplace — architected it, shipped it, and still run it. And I deliver for clients: a full D2C e-commerce platform, spec to production, someone else's requirements and someone else's business. Then I went deep into agentic AI — LLMs, RAG systems, and autonomous agents on Claude AI and the OpenAI Agents SDK.
Businesses hire me when they want intelligence that acts, not demos that impress.
