Shivam Mishra

I’m a Backend Developer with 2+ years of experience designing and optimizing scalable, high-performance Java systems. I focus on building secure APIs and reliable microservices that meet real production needs.

In my recent role, I architected Java + Spring Boot microservices for ANTlabs WiFi session management across 20+ hotels, supporting 30,000+ concurrent sessions with 99.9% uptime. I also built OAuth 2.0 and JWT-based authentication/authorization using Spring Security to satisfy enterprise security audit requirements.

At Tech Mahindra, I optimized core backend performance by tuning Java + MongoDB queries and indexing, achieving a verified 80% reduction in API response time (from ~2,000ms to ~400ms). I improved data pipeline accuracy from 48% to 95% through schema redesign and data quality initiatives, driving a 68% improvement in downstream ML model prediction performance.

I’ve also delivered measurable outcomes through well-tested, production-grade REST backends—like reducing API error rates by 20% using Postman + JUnit across 30+ endpoints. I enjoy ownership of performance, security, and maintainability, and I work comfortably across cloud and DevOps practices such as Docker, Kubernetes, and CI/CD.
