Rockstar🎓
Top SchoolPhilip Gichuhi is a back-end software engineer with 10 years’ experience, currently building open-source developer tooling at Microsoft in Nairobi focused on SDKs for the Microsoft Graph API. He designs and ships PHP-centric solutions—ranging from an OAuth2 authentication package and PHP SDK releases generated by Kiota to resilient HTTP middleware like retry and compression handlers—demonstrating a pragmatic focus on reliability and developer experience. His contributions include modernizing test suites, upgrading PHP compatibility, and improving error handling in high-profile repos such as microsoftgraph/msgraph-sdk-php and microsoft/kiota. Equally comfortable refactoring core HTTP logic and engaging the community, he blends deep computer science foundations with hands-on engineering to make SDKs more robust and easier to adopt.
