Top SchoolJuan De Alba is a Senior Software Engineer based in Madrid with nine years of experience building robust backend systems, test automation, and CI/CD pipelines across multiple languages including Ruby, JavaScript, and Python. At Datadog he has advanced application performance monitoring clients, improving tracing, test instrumentation, and CI visibility across dd-trace repos for Ruby, Node.js, and Python. His background spans startups and enterprise teams, from GNSS signal processing and C/C++ systems to modern web stacks with React, GraphQL and Django, reflecting a rare blend of embedded-systems rigor and cloud-native engineering. He consistently focuses on observability and reliable test infrastructure, adding metadata, framework versioning, and coverage integration to increase trace fidelity and CI robustness. Fluent in cross-functional collaboration, he helped scale an acquisition-era engineering team (Undefined Labs → Datadog) while continuing active open-source contributions to high-impact Datadog projects. Colleagues value his enthusiasm and pragmatic problem-solving that bridges low-level detail with production-grade tooling.
