Hey, I am Jai Soneji
Application Developer @IBM
I am a Full Stack Developer with 5+ years of experience building scalable, high-performance web applications across Banking, NBFC, and Ad-Tech domains. From architecting modular frontends for high-security Internet Banking platforms to delivering features for content platforms with 25M+ monthly active users, I've had the opportunity to work on meaningful, high-impact products alongside talented teams.
My expertise spans the full frontend spectrum — React 18, Redux, Redux-Saga, Vue.js, TailwindCSS, and SASS — with a strong focus on performance optimization, modular component design, and state management architecture. I've driven measurable results like boosting Lighthouse scores from 70 to 90+, improving Core Web Vitals to 99%, and reducing duplicate UI logic by 30% through reusable component systems.
Beyond the frontend, I've extended my work into backend development — designing and building secure REST APIs using Java Spring Boot for banking workflows, and building internal tooling that meaningfully improved developer efficiency. I'm always exploring new technologies to stay sharp in this fast-moving landscape.
