Senior Backend Engineer scaling event-driven microservices with Java and Kafka.
IndiaWhat I'm looking for
I’m a Senior Backend Engineer with 7+ years of experience designing, building, and scaling distributed, event-driven systems across e-commerce and enterprise domains. I enjoy deep system design and practical problem-solving with strong fundamentals in data structures, algorithms, and engineering fundamentals.
In my current role, I designed, developed, and owned two core microservices (Inventory & Order) for a large-scale e-commerce platform—enabling real-time order placement, stock reservation, and fulfillment tracking. I implemented workflows that reduced order processing latency by 20% and built inventory automation that reduced stock out incidents by 20%.
I also define and monitor SLOs and NFRs, performing load tests and tuning database queries to enhance throughput. My work focuses on reliability, performance, and clear operational ownership across microservices, REST APIs, and event-driven flows.
Earlier, I enhanced and scaled Oracle Fusion HCM’s payroll module for employee lifecycle management at massive scale (40 million workers across 14,000 organizations in 40 countries). Before that, I built backend services that improved engagement and onboarding speed, and transitioned large systems from monolithic architecture toward microservices.
