Performance Engineer

Responsibilities:

• Gathered requirements from business teams and stakeholders, prepared test plans.

• Analyzed metrics shared them to customers for better understanding of issues before releases.
• Analyze the tomcat server metrics - JVM Heap Usage metrics: Used Heap after Collection, %time spent in GC, Young Generation Usage, Old Generation Usage, Perm Gen Usage; Process CPU.
• Prepare the consolidated test report for each executed load test in MS Word, MS Excel & Email format after completion of analysis.
• Track and Tabulate the defects pertaining to Key Performance Indicators not meeting the historical baselines test results/SLAs and functionalities not working as expected during manual validation after code deployment
• Support Testing in Production region to replicate the Prod issues (P1 tickets) in Test region then validate the fix and provide Sign-Off. The P1 tickets were mostly about the ones listed below:
• Unhealthy Heap usage - Heap memory not getting fully reclaimed after GC - fix here involved enabling of Multi-threading on JRuby Single Container that utilized the thread local storage space effectively after Invocations and GC.
• Connection termination with CPU reaching threshold of 85% - fix here involved Optimization of Search Java Code that avoids duplicate calls hitting the DB.
