About

Backend Software Engineer with 3+ years building scalable, high-performance distributed systems. As a Senior Software Engineer at FiftyFive Technologies, I design and ship production backend microservices in Java and Spring Boot, running at 99.9% uptime. What I do: • Architect microservices with Spring Boot, Spring Cloud, and Apache Kafka for reliable, event-driven communication • Build low-latency, high-throughput services using gRPC and REST APIs • Deploy and scale with Docker, Kubernetes, and AWS • Optimize performance — cut API response times by 40% via Redis caching and PostgreSQL query tuning • Support cross-platform API development for Android and iOS apps Core tech stack: Java | Spring Boot | Spring Cloud | Microservices | Apache Kafka | gRPC | REST APIs | Redis | PostgreSQL | Docker | Kubernetes | AWS | System Design | Distributed Systems I hold a B.Tech in Computer Science (8.6/10) and am pursuing an MTech in Artificial Intelligence at BITS Pilani — pairing strong backend engineering fundamentals with applied AI/ML. I also write about backend engineering, system design, and distributed systems here on LinkedIn (sharding, consistent hashing, Spring Security, and more). Open to Backend / Software Engineer roles and open to relocation. Feel free to connect or reach out via the contact info on my profile.
