What I'm looking for

I'm seeking an immediate Backend Engineer or Java Engineer role where I can build secure, scalable microservices, high-performance REST APIs, and reliable asynchronous workflows.

I've built and maintained Java and Spring Boot APIs at 9Envoy Technologies, reducing API errors by approximately 20% through validation, exception handling, and versioning.

I designed JWT authentication and role-based access control across backend modules, eliminating unauthorized access incidents. I also built RabbitMQ-driven workflows that cut synchronous processing time by 35% and Hazelcast caching that improved API performance by 30–40% for endpoints handling 10,000+ requests per day.

For a Loan Aggregator Platform, I architected microservices for KYC, onboarding, and document validation, processing more than 1,000 verifications daily. I've also delivered interview-management workflows and a knowledge platform with Typesense search and RBAC-secured document management.

I'm comfortable improving MySQL and PostgreSQL performance, building GitLab CI/CD pipelines, and creating Prometheus and Grafana dashboards for proactive monitoring.
