PROFILE
Juan Antonio Fernández De Alba
Worked on enhancing test reliability and telemetry efficiency across DataDog repositories, focusing on backend and CI/CD improvements. In DataDog/system-tests, optimized the telemetry configuration shape to improve the relevance and efficiency of data collected for test performance analysis, leveraging Java and YAML for configuration management and test automation. In DataDog/libdatadog, replaced a GitHub Action-based JUnit results upload with a custom Bash and Python script, increasing control over CI artifact handling. Also introduced a branch parameter for test management in DataDog/dd-trace-java, enabling more granular tracking of test results. All changes emphasized traceability, robust automation, and streamlined feedback cycles for development teams.
