QA Lead / Project Manager /SRE Architect

Confidential

Responsibilities:

  • Lead the SRE Performance Engineering team to test, analyze and tune, with a focus on large scale, Infrastructure services improve an eDiscovery software, while also transforming performance quality practices and enabling delivery teams with tools and advice to account for performance as a key non-functional requirement.
  • Played an integral role in establishing over a dozen performance SLAs paving the path to ensuring engineering teams are developing the product, keeping SLA standards in mind.
  • Enhanced Load runner scripts by applying correlation rules (Manual and Auto correlation) and Parameterization rules where ever necessary to make sure the script works with multi users.
  • Created Loadrunner scenarios based on work load and executed load tests (Performance/Scalability and Endurance(Longevity)) tests to make sure the application is scable and stable for longer durations.
  • Identified CPU and Memory issues during Scalability and Endurance tests and provided better recommendations to the production team.
  • Ensured performance testing and tuning approaches evolved, as focus shifted from on-prem testing to a distributed system of Confidential CRM applications. Performed Incident Management duties during incident time and identified provide solution with zero downtime solution (Not impacted to customers).
  • Analyze JVM Heap utilization, system resource utilization trends, method hot spots identification using Dynatrace APM tool.
  • Capture Thread dumps and Heap dumps using Dynatrace tool and analyze stuck thread issues with help of Dev team.
  • Counting for system level end to end testing, even catching defects (memory leak during concurrent load scenarios) that are missed by team branch level testing. All initiatives were business value driven leading to data transfer and processing speeds to increase 25% and tuning and testing efforts that led to support over 500 users in the SaaS offering of Relativity.
  • Continuously led the team to analyze, plan and execute production-like simulations across all major workflows to identify & remediate performance problems, prevent production slowness, and guarantee predictable performance.
  • Monitored loadtests using AppDymancs/DynaTrace/OEM / splunk tools and cross checked with prod log response times.
  • This also kept the release quality at a high standard since all SLAs had to be met before the software is released to clients. Examples include SLAs defined for eDiscovery Processing, Imaging and Productions as per industry standards.
  • Developed Performance scripts using Jmeter.
  • Conducted Weekly meetings with team about current project status and Deliverables.
  • Scheduled 1-1 meetings with Team and attended all the meetings that are handled by my team with updated presentations (Shared with All the Management Teams about progress).
  • This included adaption to new infrastructure and provide analysis and recommendations to engineering for optimal configurations to ensure workflows are both scalable and cost efficient. Certain mass operations time was cut in half based on determining scaling limited and overcoming performance bottlenecks that didn't exist on-prem and Cloud but were relevant in the SaaS offering. This also led to significant cost savings up to 50%.
