What I'm looking for

I’m looking for a backend role where I can build Java/Spring Boot microservices, improve latency and reliability, and collaborate across teams. I’d also like to work on GenAI-powered features using LangChain/RAG.

I’m a results-oriented Backend Developer with 3+ years of experience architecting and delivering scalable, high-performance microservices using Java and Spring Boot. I focus on clean design with SOLID principles and layered architecture to keep systems modular and easy to maintain.

In my current role, I’ve designed REST APIs for Complaint Management and Sample Flow, improving operational efficiency by 30%. I’ve also built an OTP service using Redis with TTL-based key expiry, reducing OTP verification response time to under 50ms.

I’m especially proud of performance and delivery outcomes: I optimized JPQL queries and database indexing to cut API latency by 30%, reduced downtime by 15% through AWS CI/CD monitoring and EC2 log analysis, and cut release cycles by 20% by coordinating with frontend, QA, and DevOps teams. I also mentor junior developers to improve team throughput by 25% and I’m a GenAI enthusiast applying modern LLM tooling like LangChain and RAG.
