About Me
I build things
for the web
I'm a frontend developer with 10 years of experience turning complex problems into clean, intuitive products. I care deeply about performance, accessibility, and the tiny details that make an interface feel alive — with solid backend experience to back it up.
I have deep experience in the Fintech domain, building products for banking, payments, and financial data — where reliability, security, and precision are non-negotiable.
