What I'm looking for

I want to build modern, performance-focused web UIs with React—shipping real features, maintaining clean architecture, and backing work with strong testing. I’m excited to contribute to products where responsiveness, quality, and scalability matter.

I’m a Frontend Developer with hands-on experience building production-ready React.js applications. I’ve delivered full-featured SPAs like WatchFlix with AI-powered semantic search and real-time authentication.

I’m deeply focused on performance and quality. For example, I reduced API latency by 25% and load time by 30% in WatchFlix using React memoization, and I delivered 90%+ test coverage in BiteSwift with React Testing Library and Vitest.

I enjoy creating clean, maintainable UIs using modern frontend patterns—custom hooks, reusable components, responsive layouts, and code splitting. In BookVerse, I improved reload speeds by 35% with memoized API calls, lazy loading, and shimmer placeholders.

Beyond the frontend, I also built a modular REST API for Task CRUD using Node.js, Express.js, MongoDB, JWT auth, bcrypt hashing, and Zod validation. I’m a self-directed learner who spent 2+ years mastering the modern frontend ecosystem through real project delivery, with strong fundamentals in DSA, responsive design, and performance optimization.
