PROFILE

Mori Bellamy

Over a two-month period, contributed to LaunchDarkly’s go-server-sdk, js-core, dotnet-core, and ldcli repositories by building cross-SDK telemetry for time-to-first-token metrics and improving codebase maintainability. Developed and integrated performance monitoring features in Go, TypeScript, and C#, enabling unified SLA insights for streamed AI token generation. The work included designing instrumentation, extending interfaces, writing unit tests, and updating CI workflows for stability. Additionally, refactored ldcli’s dev-server UI by renaming components and updating imports, while enhancing repository hygiene through improved file management. These efforts improved observability, developer experience, and laid the foundation for future optimizations and onboarding efficiency.

January 2025 performance summary: Implemented cross-repo time-to-first-token telemetry across Go, JS, and .NET SDKs to enable performance monitoring and SLA insights for streamed AI token generation. Key features delivered include timeToFirstToken measurements in Tracker (Go), LDAIConfigTracker (JS), and LdAiConfigTracker (C#), with corresponding metrics integration, interfaces, unit tests, and CI updates. No major bugs fixed this month; stability improvements focused on CI and telemetry stability. Overall impact: provides actionable visibility into token-generation latency, enabling targeted optimizations, capacity planning, and cost management across services. Technologies demonstrated: instrumentation design, telemetry integration, interface extension, unit testing, and CI workflow hardening.
