About
I build commerce systems that look premium and perform under pressure.
I moved from template-focused development to outcome-led engineering after seeing beautiful stores miss revenue goals. Today, every build is designed around conversion flow, speed, and maintainable architecture so teams can scale without expensive rewrites.
