About
Hi, I’m Vishwambhar 👋 — a backend engineer who enjoys turning complex problems into simple, scalable solutions. I believe good engineering isn’t just about writing code, it’s about building systems that people can rely on every day.
Over the past few years at U-next Learning, I’ve worked across different challenges — from building a helpdesk system that supported 100K+ learners, to scaling an online coding platform to handle 50,000+ concurrent users. Along the way, I’ve optimized APIs (cutting response times by 57%), built distributed caching with Redis (reducing CPU usage by 37%), and designed AI-powered features that boosted engagement by 80%. I’ve also enjoyed mentoring interns and leading small teams, making sure projects move fast while staying clean and reliable.
What excites me most is the intersection of scalability, performance, and user impact. I love working on microservices, event-driven systems, and backend optimizations — but equally, I enjoy seeing how those technical wins improve real-world experiences. Looking ahead, I’m eager to take on opportunities where I can design at scale, mentor engineers, and contribute to products that impact thousands (or millions!) of users. 🚀
