Sanjay Kumar — Frontend Engineer

I’m a dedicated software developer with 3 years of experience in front-end development, specializing in React Native, React.js, and Vue.js. I excel at building scalable, user-centric applications using JavaScript, TypeScript, HTML5, CSS, and JSON, with expertise in REST API integration, npm, and yarn for package management. A key milestone is single-handedly developing and deploying a React Native mobile app from scratch to production on iOS and Android, using Android Studio for native configurations. This cross-platform development project involved crafting responsive UI/UX designs, managing state with Redux.js, parsing JSON data via REST APIs, and optimizing performance with Webpack and Babel. Leveraging Git for version control, I ensured a robust deployment, showcasing my skills in full-cycle mobile app development. My technical core is built on JavaScript (ES6) and TypeScript, driving dynamic solutions in React.js and React Native. I use npm and yarn to streamline dependencies, Redux.js for state management, and Android Studio for debugging and native module integration. With CSS and HTML5, I create adaptive, visually rich interfaces. I also implement Google Analytics for user behavior tracking, enhancing engagement through data-driven insights. I’m proficient in REST API integration, handling JSON payloads to connect front-end and back-end systems seamlessly. My experience spans unit testing, Agile workflows, and performance optimization, ensuring high-quality code. Whether it’s React.js for web, React Native for mobile, or Vue.js for versatile UIs, I tackle challenges like asynchronous programming, lazy loading, and bundle optimization with precision. With a passion for innovation, I stay current with tools like Webpack, Babel, and Git, refining my craft in cross-platform development. My holistic approach—blending UI/UX design, JSON parsing, and technical agility—delivers impactful results. Let’s connect to explore how my expertise in React Native, Android Studio, and front-end development can elevate your projects!
