Performance Engineer — Quantum Cloud Systems

San Francisco, CA | March 2023 – Present

• Executed 24 large-scale distributed load tests using Apache JMeter, simulating up to 150,000 concurrent users to identify memory leaks and database deadlock issues before the holiday sales peak.
• Re-architected JVM memory management and garbage collection settings for 12 core microservices, resulting in a 28% reduction in heap usage and reclaiming $45,000 in monthly container hosting fees.
• Established automated execution of Gatling performance suites within GitLab CI/CD pipelines, lowering average load verification cycle times by 32% and ensuring zero major regressions per release.
• Configured Prometheus monitoring and Grafana dashboards for a high-traffic payment gateway, enabling real-time alerting that reduced mean time to detect (MTTD) performance degradation by 40%.

Performance Test Engineer — Vanguard Digital Group

Chicago, IL | September 2021 – February 2023

• Conducted deep-dive performance analysis on 8 legacy database schemas, optimizing SQL query execution paths to improve transaction throughput by 35% and reduce lock contention by 42% under load.
• Collaborated with 6 software development squads to run scalability assessments using NeoLoad, validating application capacity and defining hardware requirements for a cloud migration initiative.
• Configured APM monitoring using Dynatrace across 3 test environments, mapping end-to-end user transactions and pinpointing method-level latency bottlenecks to improve rendering times by 18%.
• Maintained a central repository of 50+ reusable testing scripts, streamlining framework setup and saving the engineering division an average of 15 hours of manual preparation per project cycle.
