PROFILE
Juan Antonio Fernández De Alba
Juan Fernandez focused on backend and DevOps engineering across DataDog’s system-tests, libdatadog, and dd-trace-java repositories. He optimized telemetry configuration in system-tests, refining the data shape to improve the relevance and efficiency of test performance analysis using Java and YAML. In libdatadog, he replaced a GitHub Actions-based JUnit results upload with a custom Bash and Python script, increasing reliability and control over CI artifact management. Additionally, he enhanced test management in dd-trace-java by introducing branch-level tracking for test optimization. Juan’s work demonstrated depth in configuration management, CI/CD, and test automation, addressing reliability and data quality in distributed testing environments.
