Backend Engineer building scalable, event-driven microservices for production systems.
IndiaWhat I'm looking for
I’m a Backend Engineer with 3+ years of experience designing and operating distributed, event-driven systems in production environments. I focus on building scalable microservices across real workflows like multi-warehouse fulfillment, procurement, and large-scale merchant onboarding.
I’ve led and owned core backend modules, shipping end-to-end features such as a Service Purchase Order capability that reduced manual effort by 60% and improved procurement compliance and audit readiness by 25%. I’m especially driven by observability, performance optimization, and reliability in high-throughput systems.
From secure, stateless authentication with JWT/OAuth2 and monitoring-driven uptime improvements to caching, indexing, and logging frameworks that cut debugging time by 30%, I build systems that stay fast and maintainable as traffic grows. I enjoy cloud-native architectures using Java/Spring and Kafka, and I bring a practical engineering mindset shaped by production delivery.
