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.

March 2025 focused on stabilizing OpenAPI tooling, strengthening code-generation pipelines across .NET, TypeScript, and multi-language targets, and hardening CI/CD to reduce build noise. The month delivered correctness improvements for OpenAPI documents, more robust Copilot-enabled generation paths, and infrastructure fixes that reduce public API risk and improve developer productivity across multiple repositories.

December 2024 monthly summary: Delivered two high-impact bug fixes and a reliability improvement across microsoftgraph/msgraph-sdk-python-core and Philippus/kiota. Implemented AsyncClient proxy handling fix with httpx.Transport changes (commit f7de8527ad18badc91ffdb5b9888eef9fb0e3882) and corrected allOf inheritance handling for primitive types in client generation (commit 9767b3ff16673faf0b793b47c58160bd47dcb1fe). Result: more reliable proxies in Python clients, stable test suites, and safer code generation with better enterprise applicability.
