About

Software Engineer with 2+ years of experience building scalable, high-performance web applications using React.js, JavaScript,Next.js, Typescript and MERN Stack (MongoDB, Express.js, React.js, Node.js). On the frontend, I specialise in building responsive single-page applications with React.js and Redux, with a strong focus on Web Performance Optimization — Core Web Vitals (LCP, FCP), lazy loading, code splitting, and Lighthouse audits. I also work with Next.js for server-side rendered React applications. On the full-stack side, I design and deliver complete features end-to-end — building RESTful APIs with Node.js and Express.js, integrating MongoDB, and working with event-driven architectures and third-party API integrations. I have working experience with both SQl and No-SQL Databases. I have built and shipped production systems at both startup scale (Ten20 Infomedia) and enterprise scale (Oracle) — giving me strong foundations in writing clean, maintainable JavaScript across fast-moving and large-scale environments. I have worked on building products as a side projects in my free time using AI tools like Claude, Codex, AntiGravity etc. Currently open to FullStack Engineer, Frontend Engineer and Backend Engineer roles. 📩 Feel free to reach out through my email - chetansai.official@gmail.com.
