As Bakkt's Lead SDET of Performance Engineering, my remote role involves overseeing all aspects of performance testing for the Marketplace & Loyalty domains, including planning, scripting, execution, analysis, & reporting. I successfully led the transition from Gatling to JMeter for our performance testing, enhancing the effectiveness & efficiency of our processes.A significant aspect of my role includes using Perfecto mobile automation for in-depth performance analysis, covering device metrics, logs, & response times with network virtualization. I craft automation scripts in IntelliJ IDEA & manage manual executions on the Perfecto web cloud, ensuring a comprehensive testing process.I streamlined our performance testing process by integrating Azure with Jira, taking ownership of story, task, & bug tracking for our Performance testing epic. Furthermore, I've established a robust Azure DevOps pipeline for on-demand performance testing regression, including server monitoring & API log analysis with Azure AppInsights for swift issue identification.A distinctive aspect of my work involves the analysis of Production API logs to identify the top 35 API hits. This information forms the basis for creating similar performance testing scenarios at a business level, ensuring that our performance testing aligns closely with real-world usage patterns.I use Confluence for robust performance reporting, facilitating clear documentation of our testing outcomes. Working within an Agile Scrum framework, I excel in a dynamic, collaborative environment, adapting seamlessly to evolving project & team needs.I've played a vital role in migrating to Google Cloud (GCP) for the Marketplace & Loyalty domains, gaining crucial Kubernetes exposure for configuration optimizations in lower environments.

In my role as a Senior Performance Engineer at Amdocs, based in San Diego (but working remotely), I had the unique opportunity to leverage my expertise to mentor, advise, troubleshoot, and optimize performance tasks and teams. This encompassed a range of responsibilities, including conducting extensive performance testing for ATT's web applications and APIs/XMLs across multiple environments. I oversaw critical phases such as shakeout/smoke, ramp up/breakpoint, mixed flat run, and stability/endurance tests, ensuring the highest standards of performance. To accomplish these tasks, I effectively utilized industry-standard tools such as LoadRunner and Eggplant Performance for precise scripting and efficient test execution. Additionally, I employed SQL developer tools for meticulous database data verification and accurate error tracking, contributing to our rigorous testing and quality assurance processes. My proficiency in Linux basic commands proved instrumental in facilitating machine access and log tracing during troubleshooting, ensuring swift and effective resolutions to any issues that arose.Beyond my core responsibilities, I undertook a noteworthy side project during my time with Amdocs. I embarked on the development of a custom automation framework using Selenium WebDriver (C#, Nunit, Visual Studio). This innovative framework was specifically designed for address search and page capture in PDF format on ATT's website, showcasing my commitment to driving improvements and delivering value beyond the scope of my primary role.My dedication to enhancing performance and my ability to adapt and innovate within the field made a meaningful impact on the teams I worked with and the projects I contributed to.══ SPECIALTIES ══ Performance Testing | Test Execution | Troubleshooting | Performance Optimization | Mentorship | LoadRunner | Eggplant Performance | SQL | Linux Commands | Automation Framework Development
