I graduated from Cornell University with a BA in Computer Science with a double major in Music and a minor in Arabic. Since August 2023, I have been working full-time as a Software Engineer at Microsoft in the Sign Engineering Team within the Product Release & Security Services (PRSS) organization.

My team is responsible for cryptographic code signing for all of Microsoft's supply chain software prior to public release, as well as managing signing services for third-party use through Artifact Signing. I am pre-dominantantly working on the Artifact Signing service where I serve as the team's subject matter expert (SME) for the control plane.

Support for n-1 Key Versions for Cryptographic Certificate Profile's Lifecycle

Main Software Designer & Engineer • September 2024 - November 2024

Artifact Signing @ Microsoft

Problem Solved: Designed and developed a solution to address a unique problem that caused a signature mismatch during batch signing operations just before the turn of the new day during the certificate renewal process.
Impact: This is a required feature fix for multiple code signing scenarios, including COSE (a cryptography standard), AI Content Provenance, and other critical use cases. This change was critical and has the scope of all Artifact Signing customers.
Process: Designed a comprehensive and non-trivial key versioning system that includes both the current and previous key versions to ensure smooth transitions in case of signature mismatch. Testing this feature proved non-trivial and required much virtualization and utilization of Moq in xUnit. Completed multiple rounds of code reviews with senior engineers during production while incorporating their feedback and enhancing the security-critical code.
Deployment: This feature has since been deployed to all production regions, enabling seamless certificate rotation for Microsoft's code signing infrastructure.
