Worked on the discord/opentelemetry-erlang repository to deliver runtime control over OpenTelemetry instrumentation, enabling the application to skip startup and supervision when the OTEL_SDK_DISABLED environment variable is set. This backend development effort in Erlang focused on reducing startup overhead and minimizing unnecessary instrumentation, improving both deployment safety and observability configurability. Addressed a compatibility issue by restoring the missing export for record/5 in otel_meter_noop.erl, ensuring correct operation across environments. The work emphasized environment configuration and observability, resulting in a more maintainable codebase that allows operators to toggle instrumentation dynamically without code changes, supporting safer and more flexible production deployments.
