What I'm looking for

I’m looking to lead frontend engineering on secure, high-impact products—building scalable architectures with Angular/React, strong state management, and accessible UI, while mentoring teams and collaborating across product, backend, and compliance.

I’m a Frontend Lead who builds secure, production-ready frontend for financial platforms—supporting loan collection and recovery used by internal operations teams. At Mida Technologies, I drive delivery quality, architectural improvements, and technical mentorship while collaborating with backend, product, and compliance to align features with financial regulations.

I designed scalable frontend architectures and improved feature development speed by ~30% through reusable components and shared patterns. I execute state management with NgRx and RxJS, reducing UI bugs and inconsistent state issues by ~40%, and I integrate data visualization dashboards (ApexCharts) to surface loan performance metrics and strengthen operational visibility.
