About me

Full stack engineer building SaaS products and AI features.

I'm a Full Stack Engineer with 4+ years of experience building production SaaS platforms across real estate, e-commerce, and deal management. I've delivered 15+ projects for multiple clients, from multi-role dashboards and admin portals to AI features built on the Claude API, taking each one from database design to deployment.

I care about more than making code work. I focus on understanding the underlying problem, handling edge cases, and shipping features that are practical to maintain. Most of my work is private client work, so the public projects below show my independent work, and project details are generalized.
