About

I am a Frontend Developer with 7 years of specialised experience delivering enterprise-scale applications and high-performance Single Page Applications (SPAs) for global clients like American Express, Apple, and Citi Bank. My core expertise is translating complex business logic into secure, scalable, and delightful user experiences: Core Tech Stack: Expert-level proficiency in React (including modern Hooks and Microfrontends), Angular (v20, NgRx Signals, RxJS), Vue.js/Nuxt.js, TypeScript, and modern JavaScript. Enterprise Security: Proven ability to build and implement secure authentication workflows (token-based auth, login/logout, session timeout, guard services) for sensitive user data, ensuring system integrity and security. Performance & State: Deep understanding of state management using NgRx Signals, RxJS, Redux, and Pinia, coupled with optimization techniques (e.g., Code Splitting, Lazy Loading) to deliver fast, highly performant applications. Measurable Impact: I've driven significant results, including boosting analytics accuracy by 25% through Amplitude event tracking , and achieving a 20% performance increase by modernizing legacy applications. I thrive in Agile/Scrum environments and am adept at both developing core frontend features and resolving critical production incidents (achieved 99.9% uptime and 95% SLA compliance).
