PROFILE

Andrew Omondi

Andrew Omondi engineered robust improvements across Microsoft’s Kiota and Graph SDK repositories, focusing on API client stability, code generation, and CI/CD automation. He enhanced Python and .NET SDKs by modernizing type handling, strengthening serialization, and aligning with evolving platform standards such as Python 3.9+ and .NET 9.0. In microsoftgraph/MSGraph-SDK-Code-Generator, Andrew automated secure PR workflows and refined multi-language build pipelines, while in Philippus/kiota, he addressed code generation correctness for Java and Dart. Leveraging C#, Python, and Java, his work emphasized maintainability, test coverage, and build reliability, demonstrating deep technical understanding and a methodical approach to complex SDK ecosystems.
