Senior Software Engineer II @ MakeMyTrip | ReactJS, React Native, TypeScript, NextJS, NodeJS | Building Frontend Systems at Scale (200K+ Daily Users) | Ex-OnePlus, Ex-Recykal

About

I build frontend and backend systems that handle real scale — currently leading frontend architecture and backend systems work for Ground Transport (Rails) at MakeMyTrip Group, where my team's work touches 200K+ daily travellers and 60,000+ daily train bookings. Over 5+ years across MakeMyTrip, Recykal, and OnePlus, I've specialized in React.js, React Native, Node.js, TypeScript, and NextJS — building isomorphic web architectures, monorepo systems, backend services, and high-performance SEO-driven UIs. A few things I'm proud of: → Led revamp and porting of the Client Backend Layer to Node.js, cutting infrastructure cost by $200+/day → Re-architected a SEO page that drove a 40% increase in CTR through Core Web Vitals optimization → Introduced a monorepo architecture across frontend teams, cutting onboarding time by 30% → Built test coverage frameworks (Jest, RNTL) from scratch, raising component test coverage to 45% → Built an AI-powered support chatbot (Resolvitron) that cut on-call escalation effort by 30% I care about performance, clean architecture, and shipping things that move real business metrics, not just code that works. Always happy to talk full-stack architecture, React ecosystem trends, or scaling consumer apps. Tech stack: ReactJS, React Native, NodeJS, TypeScript, JavaScript, Redux, RTK Query, NextJS, Material UI, ExpressJS, Jest, Jenkins, Git
