Product thinking. Engineering execution.

I've spent 10+ years building, leading, launching, and growing zero-to-one products across startups and technology teams.

My foundation is product, understanding problems, validating opportunities, designing systems, aligning teams, and getting products into users' hands.

As AI changed what became possible, I chose not to remain a product leader who only manages technical execution. I went deeper into the engineering layer, learning to architect AI systems, build software, work with models and agents, manage infrastructure, and ship production products myself.

Today, I work across the full product system: Strategy → Product → AI → Engineering → Growth.

I build products myself, lead teams building larger systems, and experiment with how AI changes the way products are researched, designed, engineered, tested, and operated.

Build to understand.

I approach product with a founder's mindset: stay close to the problem, understand the system, and turn insight into something people can actually use.

I learn by building. I test assumptions, break things, rebuild them, document what works, and carry those lessons into the next product.

For me, product, engineering, and growth are not separate conversations. They are different parts of the same job: turning insight into impact.

Let's talk product.

I'm open to conversations around AI products, product leadership, technical product roles, ambitious zero-to-one problems, and teams building what comes next.
