Kumari Dhananjaya

I am a Frontend React Developer with 5.2 years of professional experience in building modern, scalable, and user-centric web applications. My core expertise lies in React.js, TypeScript, JavaScript (ES6+), Redux, and Next.js, with a strong focus on performance optimization, clean architecture, and reusable component design.

I have worked on enterprise-level and high-traffic platforms for global clients such as British Telecom (EE.co.uk), Shopify, and Healthline, where I contributed to developing responsive, accessible, and high-performing user interfaces. These projects required close collaboration with designers, backend engineers, and product managers in agile environments, ensuring timely delivery and high code quality.

My technical skill set includes building Single Page Applications (SPAs), implementing routing using React Router, and managing complex application state using Redux, Redux Toolkit, Context API, and middleware like Redux-Thunk. I am proficient in integrating REST and GraphQL APIs, handling asynchronous data flows, and ensuring smooth frontend-backend communication.

I strongly focus on performance and best practices by implementing lazy loading, code splitting, memoization, and efficient rendering techniques. I also have hands-on experience writing unit and integration tests using Jest and React Testing Library, helping maintain application reliability and long-term scalability.

From a UI/UX perspective, I am experienced in developing responsive designs using HTML5, CSS3, Sass, Bootstrap, Material UI, and modern styling approaches. I follow accessibility standards (WCAG) to ensure inclusive user experiences across devices and browsers.

In addition to development, I actively participate in code reviews, bug fixing, and continuous improvement initiatives. I am comfortable working with version control systems like Git, modern build tools such as Webpack and Babel, and CI/CD pipelines using Jenkins.

I am passionate about writing clean, maintainable code and staying up to date with evolving frontend technologies. Currently, I am seeking remote or challenging frontend opportunities where I can contribute my expertise, grow technically, and deliver impactful digital experiences.
