Frontend-Focused Fullstack Engineer | Customer-Obsessed Product Builder | Fintech Entrepreneur

About Me

I am a product-minded full stack engineer with 15 years of experience working closely with customers to turn complex systems into usable products. I have built data-heavy platforms in fintech, Web3, and enterprise environments, and I enjoy being close to real customer problems. My strength is understanding business needs, data flows, and technical constraints, then shipping practical solutions with strong UX. I am especially interested in roles where engineering, customer interaction, and rapid iteration come together.
