Work History
Sr. Principal Software Developer
Oracle (MySQL)
04.2005 - 09.2025
- Designed, implemented, expanded and maintained an in-house performance change testing framework for MySQL.
- Established and led a performance engineering department from the ground up – Mentored and led a team of performance engineers guiding them in using internal frameworks, handling testing requests, and following standardized procedures. Created ways for developer to have work tested before push, an automated farm of hosts looking for change in all commits and release testing. Expanded testing scope to include MySQL in Oracle Cloud, covering High Availability configurations and HeatWave creation.
- Designed and constructed a specialized testbed of hosts integrated with a custom automation framework to enable efficient and comprehensive evaluation of MySQL performance changes across various configurations, workloads and operating systems (Linux/Windows)
- MySQL Heatwave (Oracle OCI Service) Benchmark – Designed the merging of the performance framework and another in house framework responsible for OCI to combine the power of the performance change framework for testing MySQL cloud.
- Designed and implemented multi-client benchmark architecture - Testing OCI Network Load Balancer performance with MySQL Read Replicas. Identified limitations of single-client load generation and scaled testing by integrating multiple benchmark client hosts.
- Designed and implemented developer-triggered performance benchmark integrated with Gerrit review - Enabled developers to initiate basic performance tests by commenting on code reviews.
- Performed rotational duties across production monitoring, request handling, and release validation. – Oversaw the performance production farm for several months each year, investigating anomalies and changes in benchmark results. - Collaborated with developers to address performance-related requests and troubleshoot regressions. Executed release testing to ensure stability and performance consistency across MySQL builds.
