  • Develop performance test plans, test cases, and execution strategies.
  • Track performance metrics and trends over time to ensure consistency and stability of systems.
  • Performance Benchmarking
  • Perform benchmarking activities to understand and measure system performance against industry standards and best practices.
  • Application Monitoring
  • Continuously monitor the performance of applications in cloud-based pre-production environments.
  • Utilize application performance management (APM) tools (e.g., Jprofiler, Open-source tools, etc.) to detect and troubleshoot performance issues.
  • Implement observability solutions, leveraging tools like Prometheus, Grafana, New Relic, Dynatrace, or Datadog for real-time performance monitoring.
  • Troubleshooting and Issue Resolution
  • Investigate and resolve performance-related issues across multiple platforms (web, backend services).
  • Work with teams to implement effective root cause analysis for performance failures.
  • Identify, diagnose, and optimize performance bottlenecks across the entire technology stack (application, database, infrastructure, and cloud environments)
  • Automation and Scripting
    • Develop automated scripts and frameworks for creating complex financial data, load, and performance testing.
    • Leverage automation tools (e.g., JMeter, LoadRunner, Gatling) to run performance tests and gather metrics.
    • Develop and maintain performance test suites using industry-standard tools (JMeter, Gatling, LoadRunner, etc.).

 

  • Reporting and Documentation
  • Create detailed reports with analysis, recommendations, and action plans for performance improvements.
  • Maintain thorough documentation of performance tests, results, and optimization strategies.
