PROFILE

Mori Bellamy

Mori developed cross-repository time-to-first-token telemetry for LaunchDarkly’s go-server-sdk, js-core, and dotnet-core, enabling precise performance monitoring and SLA insights for streamed AI token generation. By designing and integrating instrumentation in Go, TypeScript, and C#, Mori extended existing interfaces, added new metrics, and implemented unit tests to ensure robust tracking and observability. In the ldcli repository, Mori refactored the dev-server UI by renaming components and updating imports, improving codebase clarity and onboarding. The work demonstrated depth in backend development, CI/CD, and file management, resulting in more actionable metrics, stable builds, and a cleaner development experience for future enhancements.
