Over five months, Derobuts developed and enhanced features across the microsoftgraph/entra-powershell and OData/odata.net repositories, focusing on automation and reliability for enterprise identity management. He built PowerShell cmdlets for sponsor management and service principal key credential automation, integrating with Microsoft Graph API and Azure Entra ID to streamline admin workflows and improve security. His work included implementing batch processing, dependency resolution, and robust unit testing in C# and PowerShell, as well as fixing parameter binding logic to reduce automation errors. The solutions addressed real-world admin needs, demonstrated technical depth, and improved the maintainability and correctness of backend and scripting modules.

In July 2025, delivered automation for Entra service principal key credential management in microsoftgraph/entra-powershell. Implemented New-EntraServicePrincipalKeyCredential with support for multiple credential types, usages, and validity periods, including a beta version and unit tests. This feature reduces manual credential rotation, improves security posture, and accelerates scripting workflows for admins.

February 2025: Delivered Entra PowerShell sponsor management capabilities for microsoftgraph/entra-powershell, introducing Get-EntraUserSponsor / Get-EntraBetaUserSponsor and Remove-EntraUserSponsor / Remove-EntraBetaUserSponsor for v1.0 and beta releases. This release includes unit tests and documentation, reinforcing governance and admin efficiency by making sponsor relationships observable and removable from PowerShell. Key commits anchored this effort (e.g., 9ad505ddd2a7596b83283270679e4a3bd09db700 and b4d48d6ed6256b36523f58edb2c9775076792e3f).

In November 2024, the OData/odata.net work focused on strengthening batch operations and client reliability by introducing explicit dependency support for AddRelatedObject within batch requests, complemented by refactoring and tests for JSON batch handling. The key delivery was the Add DependsOnIds feature, enabling precise sequencing of additions and dependencies across related objects, improving batch consistency and client capabilities. This work reduces integration risk for clients that perform complex batched mutations and sets the foundation for more robust batch processing in future iterations.
