Responsibilities:

●Architected and developed scalable, enterprise-grade applications using ReactJS, TypeScript, and Next.js, implementing server-side rendering (SSR) and static site generation (SSG) to optimize performance and SEO across customer-facing platforms.

●Engineered robust Redux and Redux Toolkit (RTK) state management architectures, designing normalized store structures, custom middleware, and async data pipelines using Redux Thunk and RTK Query for high-volume, real-time frontend applications.

●Built and maintained a shared reusable React component library with strict TypeScript typings, compound component patterns, and custom hooks — adopted across multiple product teams to accelerate development velocity and enforce UI consistency.

●Developed and integrated RESTful within React/Next.js applications using Axios and implementing optimistic updates, error boundaries, and request caching strategies for seamless user experiences.

●Implemented comprehensive frontend test coverage using React Testing Library and Jest, following Test-Driven Development (TDD) practices — achieving 85%+ unit and integration test coverage across critical user flows.

●Delivered TypeScript-first React codebases with strict type safety, enforcing interface-driven development, generic component patterns, and strong typing across Redux slices, API contracts, and component props.

●Built responsive and modern UI components using Tailwind CSS, leveraging utility-first styling to accelerate development, ensure design consistency, and reduce custom CSS overhead.

●Leveraging edge caching and CDN strategies to achieve optimal Core Web Vitals scores and sub-second page load times.

●Automated frontend build, testing, and deployment workflows using CI/CD pipelines (Jenkins, GitHub Actions), including lint checks, type validation, and React Testing Library test suites as mandatory pipeline gates.

●Led frontend code reviews and performance audits, identifying React-specific bottlenecks — memoization gaps, unnecessary re-renders, oversized bundles — and driving measurable improvements in Lighthouse scores and runtime efficiency.

●Collaborated within Agile/Scrum teams alongside Product, Design, and Backend engineers, contributing to sprint planning, technical design reviews, and cross-functional architecture decisions.
