Building Scalable & Impactful Software 🚀

Innovate Ideas → Design Solutions → Code Excellence → Scale Impact

Welcome to My World of Code
Crafted with Passion, Driven by Innovation

I build backend systems that run fast, scale smart, and never skip a beat.

Hey, I’m Shagun Rajput — I build cloud-native backend systems that don’t just work, they perform. I specialize in Java and Go, crafting microservices that are fast, scalable, and reliable — all backed by proven design patterns. I’ve worked with Apache Kafka, Redis, PostgreSQL, AWS, Docker, and Kubernetes, delivering distributed systems and microservices that handle serious scale without breaking a sweat. Right now, I’m diving into ML/AI to power the next wave of intelligent, data-driven apps.
