Performance Test Engineer specializing in JMeter and LoadRunner for enterprise systems.
IndiaWhat I'm looking for
I am a Performance Test Engineer with 17+ years in IT and over 5 years focused on performance testing using JMeter and LoadRunner, delivering performance validation across healthcare and banking domains. I am ISTQB certified and experienced in API performance testing, workload modelling, and bottleneck analysis.
At Ontario Health I executed end-to-end performance testing for large-scale healthcare platforms, achieved SLA targets (P95 < 2.5s), identified critical database bottlenecks and enabled production readiness through distributed JMeter testing and ELK-based log analysis. Prior roles at Scotiabank engagements and TCS include load, stress, endurance testing, memory-leak detection, and performance-driven remediation collaboration with development teams.
I actively upskill in cloud and observability tools (AWS, Docker, Kubernetes, ELK) and explore AI/ML and generative AI tools to enhance test case generation and log analysis. I seek roles where I can lead performance validation, improve system reliability, and mentor teams on performance engineering best practices.
