PROFILE
David Castañeda
Over a three-month period, this developer focused on enhancing observability and telemetry in Rust-based backend systems for the apollographql/router and apollographql/apollo-mcp-server repositories. They delivered general availability for subgraph metrics configuration, including configuration flag migrations and comprehensive test coverage, enabling safer production rollouts. Their work on the MCP server introduced OpenTelemetry middleware for distributed tracing, parent context propagation, and robust end-to-end traceability, improving monitoring and diagnostics. They also performed code maintenance, dependency cleanup, and documentation updates to support ongoing reliability. The technical approach emphasized API development, async programming, and middleware implementation, leveraging Rust, YAML, and OpenTelemetry throughout.
