Summary
A frontend engineer with solid experience in Angular and React, I’ve built scalable admin dashboards, payment pages, and authentication flows for real-world fintech and enterprise systems. From customizing user experiences to proposing better state management with NgRx, I’ve collaborated across global teams and legacy codebase. I value clean architecture, usability, and cross-functional teamwork—and I’m always eager to deliver maintainable, reliable features that users and teams can count on.
