I’m a Frontend developer with expertise in React.js and TypeScript, focused on building scalable web and mobile applications with maintainable, modular architectures. I create reusable components and optimize data fetching strategies to elevate user experience and application dependability.

As a Freelance·Independent Frontend Consultant (Jul 2025–Present), I deliver comprehensive frontend features by converting business requirements into scalable UI components with predictable data flow and clean architectural design. I also refine data fetching with pagination, caching, and error handling to boost UX consistency and reliability, using AI tools to speed up code review, debugging, testing, and documentation.

At Neenopal Inc (May 2024–Jun 2025), I refactored and modernized a large-scale SaaS frontend into a modular, maintainable architecture, increasing scalability and long-term extensibility. I built high-performance UI features with React using reusable components, structured state management, and efficient rendering—partnering closely with product, design, and backend teams.

Earlier, at Delta4 Infotech Pvt Ltd (Feb 2022–Apr 2024), I engineered scalable real-time web applications using React, Redux, and Socket.IO, improving responsive, high-performance user experiences. I enhanced frontend performance by minimizing re-renders with memoization and lazy loading, and I used Sentry and analytics tools to monitor, resolve production issues, and strengthen stability and observability.
