At OptiSol Business Solutions, I lead end-to-end performance testing and scalability sign-off for web, REST API, mobile, and database applications. I also gather requirements, define non-functional requirements, and develop test plans and workload models.

I built an AI-powered JMeter HTML Report Generator that reduced manual reporting effort by 95%, along with an AI-assisted tool for cross-run regression analysis. I maintain Grafana and InfluxDB dashboards for real-time monitoring.

At KGISL, I developed JMeter and LoadRunner scripts and integrated performance test suites into Jenkins CI/CD pipelines for unattended load tests across builds. I used Dynatrace to monitor server metrics and support bottleneck analysis.

Earlier, at Accubits Technologies Inc and kCube Consultancy Services (P) Ltd, I developed JMeter scripts, ran load and endurance tests, and monitored performance using Dynatrace, Grafana, and InfluxDB. My work has covered banking, insurance, retail, media and OTT streaming, data and AI, and e-learning domains.
