At abz.agency, I lead front-end architecture for complex browser extensions and web tools built with React and TypeScript. I also mentor developers and own feature initiatives from start to finish.

Before becoming Tech Lead, Front-End, I developed responsive interfaces and Chrome MV3 features at abz.agency, integrating REST APIs, authentication, and payment gateways including Stripe and PayPal.

I also build full-stack products, including LeLi Talent Center, a ticketing and marketing platform with online payments, QR tickets, and an admin check-in panel. My projects include Chrome extensions for iframe analysis and redirect tracing.
