Dónal O'sullivan

Worked on the elastic/opentelemetry-demo repository to deliver feature-flag support for the cart workflow, focusing on backend development using C# and OpenTelemetry. Reintroduced the OpenFeature dependency injection package and reconfigured cart services, including ValkeyCartStore, to enable feature flag management and OpenFeature-backed functionality. Restored cart/src/Program.cs to match the upstream EDOT version, ensuring consistency with ongoing upstream changes. Addressed a compilation issue caused by a merge conflict by correcting string formatting, which stabilized the build process. This work improved feature experimentation capabilities and streamlined future contributions by aligning local changes with upstream development practices and resolving integration issues.

December 2025 (elastic/opentelemetry-demo): Delivered feature-flag support for the cart workflow by reintroducing the OpenFeature dependency injection package and reconfiguring cart services (ValkeyCartStore) to enable OpenFeature-backed cart functionality. Restored cart/src/Program.cs to the upstream EDOT version to maintain consistency with upstream changes. Fixed a compilation issue caused by a merge conflict by ensuring a string stays on a single line. These changes improve feature experimentation capabilities, stabilize builds, and align with upstream merging processes for smoother future contributions.
