What I'm looking for

I’m looking for a role where I can build production-grade Java/Spring backend systems—secure microservices, Kafka-driven event flows, and performance-tuned APIs—while collaborating cross-functionally and continuing to explore agentic AI/RAG integrations.

I’m a Backend Engineer with 2 years of experience building scalable, high-performance backend systems using Java and Spring Boot. I focus on designing distributed services and production-ready APIs that are secure, maintainable, and built for scale.

At Corpseed ITES Pvt. Ltd., I’ve contributed to a Spring Boot microservices-based ERP platform handling 5K+ compliance workflows/month, including onboarding, document collection, legal verification, and regulatory licensing. I’ve refactored a multi-module monolith into microservices, implemented Feign clients across 5+ backend services, and introduced Kafka-based asynchronous messaging to move from synchronous workflows to event-driven pipelines.

Previously at Oodles Technologies, I built 25+ and 30+ REST APIs for high-traffic platforms and enterprise workforce management, improving throughput by 40% and reducing API latency by 35% using query optimization, Protobuf-based serialization, and batching. I’ve also shipped appointment scheduling integrations (5K+ provider–patient calendars/month via Cronofy), strengthened security with Spring Security/JWT/RBAC, and improved performance with Redis caching and AWS S3 for media handling.
