PROFILE
Marco Costa
Over a two-month period, contributed to observability and tracing improvements across DataDog/datadog-agent, DataDog/dd-apm-test-agent, and DataDog/dd-trace-js. Developed an OpenTelemetry enhancement for GraphQL tracing in Go, remapping resource names to include operation type and name, which improved trace granularity and debugging for GraphQL workloads. In JavaScript and Python, delivered span events support in the APM test agent by defining event structures and enhancing verification, while also fixing array attribute serialization in the JavaScript tracer. Focused on backend development, distributed tracing, and data serialization, the work strengthened instrumentation coverage and increased the accuracy of observability and testing workflows.
