What I'm looking for

I seek backend/cloud roles where I can build reliable, scalable microservices and data pipelines, improve observability and security, and drive performance and operational excellence.

I am a Backend Engineer with 4+ years of experience building scalable microservices, distributed systems, and GCP-based data pipelines. I focus on production-grade engineering, clean architecture, and secure coding practices.

At Equifax I engineered Apache Beam pipelines processing millions of records, cutting batch processing time by 45% and improving downstream data access latency by 30% through Spring Boot microservices.

Previously at TCS and UST Global I modernized Java Spring modules, refactored legacy components, optimized PL/SQL and PostgreSQL performance, and stabilized CI/CD pipelines to reduce incidents and increase deployment success.

I hold a Google Cloud Associate Cloud Engineer certification and prioritize reliability, observability, and security while delivering high-impact solutions that reduce technical debt and improve system performance.
