Software Development Engineer, Amazon Web Services (AWS) June 2020 - Present
- Pipeline Performance & Reliability: Revamped the .NET Lambda release pipeline, slashing the testing stage runtime by 99% (from over 5 hours to 7 minutes) and achieving a 43x overall performance improvement by resolving a critical deadlock bug and enabling full test parallelization.
- Automation & Tooling: Engineered and launched a novel automation tool (AutoVer) that streamlined versioning, changelog generation, and release processes for 15 high-level libraries, reducing a manual, error-prone workflow to a single-click operation via GitHub Actions.
- Infrastructure Development & Security: Architected and implemented a multi-account AWS testing infrastructure to support unit and integration tests across all team libraries. This initiative introduced automated PR checks that significantly improved code quality, developer velocity, and system reliability.
- Operational Efficiency: Enhanced system security and reduced operational toil by developing an automated test resource sweeper, which eliminated recurring weekly security tickets from orphaned resources and lowered infrastructure costs.
- Strategic Initiative Leadership: Led the end-to-end initiative to introduce ARM-based application deployment, delivering significant cost savings and performance improvements to customers by enabling more efficient compute options.
- Rapid Service Enablement: Spearheaded the .NET 8 launch on AWS Lambda by owning the OCI image release lifecycle, delivering production-ready images within hours of Microsoft's official GA release to unblock the Lambda service and ensure immediate availability for customers.
- Process Automation: Innovated a self-mutating CI/CD infrastructure for .NET Lambda OCI images, fully automating the annual runtime update process and future-proofing the release pipeline against thousands of hours of repeated engineering effort.
