I've improved production readiness for SAP Fiori and SAP S/4HANA workflows at JNET Technologies while managing global LoadRunner Enterprise infrastructure and completing a zero-downtime migration from LoadRunner Professional.

At AutoZone, I co-designed an Agentic AI workflow combining LoadRunner Enterprise telemetry and Dynatrace, reducing RCA cycle time by 40% and saving 50+ engineering hours monthly. I also designed production-scale workloads handling 3500–4000 TPS, improved API latency by 15–20%, and validated autoscaling and multi-zone failover resilience.

Previously at Gemini Solutions, I reduced end-to-end latency by 30%, automated REST collection conversion into performance scripts with Java, and increased Hartron Web Portal throughput by 25%.
