Backend Software Engineer | Immediate Joiner | Java, Spring Boot, Microservices | Kafka | Building Scalable Distributed Systems

About

I'm a Backend Software Engineer with 1.7+ years of experience building and scaling Java and Spring Boot microservices for high-throughput, production systems — including institutional banking platforms processing thousands of transactions daily. My core focus is distributed systems: designing Kafka-based event-driven architectures, building REST APIs that hold up under real load (I've maintained sub-200ms response times at 99.9% availability), and writing code that's clean enough to pass a 30% reduction in code smells through SonarQube enforcement, not just work. Technically, I work across the full backend stack — Spring Boot, Spring Security, JPA/Hibernate, MySQL, MongoDB, Redis, Kafka — with hands-on exposure to AWS, Kubernetes, and Git-based CI workflows. I care about system design (both HLD and LLD), concurrency, and building things that scale without falling over. Outside of client work, I've built end-to-end microservices projects — an e-commerce backend with Stripe payments and Redis-cached APIs, and a secure journaling platform with JWT-based auth — because I like understanding a system from database schema to deployment, not just my slice of it. Open to backend engineering roles where I can keep building systems that handle real scale, reliably.
