PROFILE

Petr Hollay

Worked on the Philippus/kiota repository to deliver a feature enabling generation and merging of multiple API plugin manifests from split OpenAPI specifications, streamlining integration for complex API projects. Applied C# and backend development skills to refactor core builder components, improving stability and maintainability by internalizing services and adopting safer initialization patterns. Enhanced code quality through targeted code generation and refactoring, including the use of unsigned integers for count handling. Addressed a bug affecting service configuration, ensuring correct wiring of plugin services. The work reduced manual effort, clarified service boundaries, and supported robust handling of multi-file OpenAPI workflows in Kiota.

May 2025 focused on delivering a robust feature for handling complex OpenAPI specifications in Kiota and strengthening builder stability for long-term maintainability. Key work includes enabling generation and merging of multiple API plugin manifests from a single OpenAPI file, plus targeted internal refactors to improve stability, encapsulation, and code quality across the Kiota builder and associated services. The combined work reduces manual effort, accelerates integration for multi-file OpenAPI specs, and lowers the risk of regressions through clearer service boundaries and safer initialization.
