Himanshu Mittal

I’m a Backend Software Engineer (SDE II) with 4+ years architecting scalable microservices and distributed systems. I specialize in Java/Spring Boot and performance work that delivers measurable impact in high-throughput environments.

At Societe Generale, I redesigned the data distribution layer with AWS S3 to eliminate redundant DB queries by 60% and cut P99 latency by 40%. I also improved resiliency by implementing Resilience4j (circuit breakers, rate limiters) on the API Gateway to maintain 99.99% availability during 2x peak traffic surges.

I lead modernization with Infrastructure as Code using Terraform and Ansible, reducing environment provisioning from 4 days to 1 day, and strengthen compliance through enforced SSO across 100+ microservices to reach 100% ISO compliance. I’ve also integrated observability with OpenTelemetry and Elastic APM to reduce MTTR by 30%, and built GenAI/RAG workflows—like an AI-powered resume-job matching engine using vector databases—to automate decision-making and cut manual screening time by 70%.
