Responsibilities
* Understanding the potential performance bottlenecks on existing complex architecture and
design the performance test strategy to address the bottlenecks.
* Direct Interaction with the clients on collecting the complete performance requirements with
different workload patterns, response time and throughput SLA.
* Creating Performance Test plan/strategy and necessary documentation for facilitating the test
cycles.
* Creating JMeter Test Scripts and performed baseline test on critical business scenarios on
production environment to quantify the concurrent user support.
* Investigating the JVM Thread dumps, Heap dumps, Memory and CPU Profiles, AWR, OEM Monitoring
and identifying the performance root cause.
* Performance tuning on WebLogic and Fatwire application servers.
* Profiling the application code and identifying the CPU and memory intensive hotspots.
* Analyzing the DB Performance using AWR/ADDM/ASH Report interpretation for different problem
context.
* Debugging the Java code to identity the performance root cause using Jprofiler CPU code
profiling.
* In-depth analysis on Hardware design and Application architecture like Oracle Webcenter,
OpenJPA, Spring, Elastic path.
* Collaborate with multiple teams to address the performance issue and resolve it quickly.
* Worked closely with customer to provide the updates on regular basis.
* Performance test execution and monitoring on the identified critical Usecases.
* Analyze the performance test results and identify the potential bottlenecks during testing.
* Prepare performance test reports and detailed walkthrough session with clients.
