About

I’m a Senior Software Engineer with 7+ years of experience building scalable, fault-tolerant backend systems across fintech, e-commerce and logistics domains. I’ve led the design of multi-tenant onboarding platforms using microservices, gRPC, and Kafka/RMQ—supporting millions of users annually with <150ms latency and 99.99% uptime. This work improved conversions by 40% and reduced integration timelines across business units. Earlier, I contributed to high-scale logistics systems, optimizing APIs to handle millions of daily transactions and integrating thousands of distributed nodes into unified infra—boosting performance by over 50%. My expertise lies in distributed systems, event-driven architecture, and cloud-native backend development using Java, Spring Boot, Kafka, Redis, and AWS. I thrive on solving complex system design problems and delivering robust, high-impact platforms. Always open to meaningful conversations around scale, architecture, and backend excellence.
