About

Over the past 3 years at a single EdTech company, I've grown from intern to owning full stack features in production — backend APIs, a cross-platform mobile app, and a Next.js web revamp that improved SEO by 40%. My day-to-day stack is NestJS, Next.js, React Native, and AWS. I've worked on queue systems with BullMQ handling 1,000+ concurrent jobs, built microservices that cut API latency by 40%, and integrated third-party APIs including Meta Business and Shiprocket. I write clean, maintainable code, take ownership of features end-to-end, and communicate well across teams. I'm not a 10x mythologist — I just show up, ship, and keep improving. I'm currently looking for a mid-level Full Stack role (remote, hybrid, or Delhi NCR) where I can keep growing on real products with a strong engineering culture. 📫 kumarvarun9811@gmail.com · 🌐 varunx.netlify.app
