PROFILE
Maximo Bautista
Max Bautista developed and enhanced distributed tracing and observability features across the DataDog/dd-trace-php and DataDog/system-tests repositories over six months. He implemented baggage header propagation and unified HTTP header tagging, using C, PHP, and OpenTelemetry to improve trace context and data governance in PHP services. Max also stabilized telemetry and CI workflows, addressing flaky tests and enabling targeted-branch testing for .NET libraries with Shell scripting and CI/CD practices. His work focused on robust configuration parsing, reliable test coverage, and cross-language instrumentation, resulting in deeper observability, improved release velocity, and more maintainable backend systems for distributed environments.
