What I'm looking for

I'm looking to build clean, scalable frontend features in a collaborative team, especially with Angular, TypeScript, API integration, reusable components, testing, and modern micro-frontend architecture.

I'm developing and maintaining responsive banking web application features with Angular, TypeScript, RxJS, Angular Signals, NgRx, and Module Federation. I integrate REST APIs, create strongly typed models, diagnose integration issues, and write unit tests with Jasmine and Karma.

At One Utilities, I built the frontend architecture for OUMS, a Next.js management dashboard used by more than 30 employees to manage over 100 quotations, invoices, and projects. I also developed web and mobile agricultural data applications supporting more than 500 crop, rice, and harvest records, and redesigned the company website with optimized Three.js animations.
