Rockstar🎓
Top SchoolGabriel Aszalos is an engineer with 11 years of experience building production-grade backend systems and developer tooling, currently contributing to Datadog’s APM integrations and the Datadog Agent that runs on tens of thousands of hosts. He combines deep Go expertise with full-stack experience from Angular/React front-ends to DevOps, having shipped tracing, exporter, and HTTP integration work across high-profile open-source projects like DataDog/datadog-agent, dd-trace-go and the OpenTelemetry Collector contrib. Gabriel has a strong track record of improving observability fidelity—preserving original trace IDs and refining exporter behavior—while also tending to documentation, test quality, and build reliability. His background spans technical lead and senior front-end roles at diverse companies, giving him a pragmatic appreciation for both UX and backend scale. Based in Cluj-Napoca, Romania, he’s an active OSS contributor who gravitates toward reliability, clear interfaces, and small but impactful fixes that reduce operational friction. An underappreciated strength is his knack for clarifying documentation and tests, which repeatedly improves long-term maintainability in the projects he touches.
