- Improved CI/CD pipelines by integrating unit testing and reducing pipeline runtime from 30 minutes to 8 minutes, while also building custom tooling that helped developers propagate commits from a main repository to submodules.
- Created automations that reduced manual work for operations teams, developed onboarding workbooks that helped new developers ramp up faster, and provided hands-on code reviews, 1-on-1 mentoring, Git lifecycle guidance, production deployments, and cross-functional support across engineering, operations, management, and third-party vendors.
- Supported SOC 2 Type 2 readiness by remediating security issues in GitHub repositories and AWS infrastructure based on Drata findings, reducing reported errors by 99%.
