About Sunny

Performance Engineer with 7 years of industry experience across large-scale performance testing, observability-driven system tuning and cloud-native platforms. I specialize in identifying application bottlenecks and driving performance optimizations across distributed environments.At Oracle, I led initiatives in automation and benchmarking, including the dockerization of internal tooling, streamlining performance report generation pipelines via Jenkins and Apex, and scaling out BI workloads. My work on the Darshan project enabled real-time, pod-level insights through data modeling and OAC visualizations—accelerating root cause analysis and improving overall fleet stability.Previously at Informatica, I built and optimized performance validation frameworks for cloud services, conducted in-depth JVM analysis (thread/heap dumps), and delivered infrastructure sizing recommendations for multi-tenant environments. My approach blends robust test strategy with deep system observability using tools like Grafana, JVisualVM, CloudWatch, and more.I’m passionate about automation, performance engineering at scale, and enabling teams to make data-driven decisions through effective tooling and insights. Specialties: Performance Benchmarking | Observability | JVM Profiling | Test Strategy | Cloud Monitoring (AWS & Oracle Cloud)| OAC | JMeter | Docker | Jenkins Tools: Grafana, PerfMon, Nmon, JConsole, YourKit, Eclipse MAT, CloudWatch Programming: Java, SQL, Shell Scripting
