About

As a Senior Software Engineer (POD Lead) with over 6 years of experience in backend development, I design and lead the architecture of scalable distributed systems, microservices, and cloud-based solutions. Skilled in Java, Spring Boot, Apache Kafka, AWS, Redis, and Kubernetes, I specialize in building robust authentication services, high-throughput pub/sub pipelines, and data engineering platforms. I collaborate closely with cross-functional teams to deliver high-impact solutions that improve performance and reliability. Key career highlights include: • Architected a microservices platform on AWS (Java/Spring Boot) that boosted system throughput by 40% and achieved 99.9% uptime. • Led development of a cloud-native authentication service for 500K+ users, enhancing security and reducing login failures by 50%. • Built a Kafka-based pub/sub data pipeline processing over 2 TB of data daily at under 50 ms latency, enabling real-time analytics. • Optimized AWS infrastructure with Kubernetes and Redis, cutting cloud costs by 30% while scaling capacity to support 3× more traffic. • Mentored and guided teams on system design and agile best practices, boosting team productivity by 20%.
