ROSU ANTONY

I’m a Senior Frontend Developer with 10+ years of experience building scalable enterprise web applications with React.js, Angular, TypeScript, and JavaScript (ES6+). I bring a strong focus on frontend architecture, reusable UI components, and delivering reliable user experiences end to end.

My work specializes in REST API integration, Redux Toolkit, Context API, and RxJS, paired with responsive design and performance optimization. I’m especially effective at translating product and UX needs into maintainable code that performs well across devices and browsers.

At Tata Consultancy Services (TCS) (2022 - May 2026), I built scalable React + TypeScript applications and migrated legacy modules to a modern React architecture to improve maintainability and reduce technical debt. I optimized frontend performance with lazy loading, React.memo, useMemo, and state-management patterns—reducing load time by 25%—and improved test coverage by 30% using Jest and React Testing Library.

Earlier, at UST Global (2015 - 2022), I developed enterprise Angular (2+) applications and implemented routing, route guards, lazy-loaded modules, and RxJS-based async data handling. I improved UI load time by 20% through optimized change detection and modular loading, while resolving critical production defects and supporting release cycles through agile collaboration with backend and QA.
