What I'm looking for

I’m looking for a backend role where I can build secure, scalable APIs and event-driven services in Java/Spring Boot and Node.js, focusing on performance, reliability, and clean architecture while contributing to production-scale products.

I’m a backend-oriented Software Engineer specializing in Java (Spring Boot) and Node.js, building secure, scalable, high-performance systems. I’ve strengthened my foundation in data structures, API design, and database optimization through hands-on work supporting 1000+ users and high-volume transactions.

In projects like EasyAir Travels, I architected an event-driven airline platform with Kafka & microservices, improved efficiency by 40% using Redis caching, and implemented secure, fault-tolerant payment flows with Razorpay & Stripe plus JWT and RBAC. Earlier, I delivered production-ready frontend components during an internship, and I’ve continued improving performance and security across full-stack features while keeping reliability and usability front and center.
