About

Senior Software Engineer with 9+ years of hands-on experience building scalable, distributed backend systems using Java 17, Spring Boot, microservices, AWS, Kafka, and Kubernetes. I specialise in designing high-performance backend services, reducing latency, improving throughput, and ensuring reliability for cloud-native applications. I have deep experience in event-driven architecture, microservice decomposition, data-processing pipelines, and high-volume ingestion systems that process millions of records with strict SLAs. My work focuses on writing clean, maintainable code, optimising performance, and owning features end-to-end—from design and development to production stability. I enjoy solving complex engineering problems, improving system efficiency, and contributing as a strong individual contributor in high-impact engineering teams. Technologies: Java 17, Spring Boot 3.x, Microservices, Kafka, AWS (EKS, S3, RDS, IAM), Kubernetes, Docker, REST APIs, PostgreSQL, MySQL, Redis, Maven, Git, CI/CD (Jenkins, GitHub Actions), Linux, Observability (Prometheus, Grafana), JUnit, Mockito. Education: Strong engineering professional with a B.Tech from IIT Guwahati.
