- Hire, train, and manage a 7-person engineering team developing, packaging, and releasing Ops Manager, a platform used by customers to deploy, automate, monitor, and backup MongoDB databases.
- Fully automated the release process and refactored the e2e test suite, increasing performance and stability, improving usability, saving 8 hours of manual QA work each month, and enabling rapid releases every 3 weeks.
- Developed and delivered a feature enabling Ops Manager to function as a proxy between source code and the internet, simplifying the customers’ setup in restricted network environments and reducing setup/support times.
- Fixed a long-standing incomplete backup issue involving Ops Manager in Azure cloud, SSL, Windows, and Linux VMs.
- Added IBM Power-series support to the Ops Manager to expand access to customers using IBM infrastructure.
- Implemented and configured OpenLDAP to run as a Docker container to execute tests in a reliable and reproducible environment with almost-zero network latency.
- Wrote a Python script to detect any credentials accidentally packaged with other files, significantly reducing the risk of accidentally publishing product access credentials/keys.
