About me

I build complex digital products without turning them into systems that are hard to maintain.

For more than eight years, I have worked across Web3, health, entertainment, and startups, leading web and mobile solutions from definition to production.

I combine product judgment with technical depth to help teams make better decisions, ship faster, and scale with confidence.
