Summary
🤩
Rockstar🎓
Top SchoolAlexandre Yang is a Staff Software Engineer based in France with nine years of experience building cloud-native, backend-focused systems and leading engineering teams. He progressed through hands-on roles at Datadog—contributing to core agent integrations and SNMP telemetry for a widely used monitoring product—and has a strong background in microservices, DevOps, and CI/CD from prior lead roles. He excels at improving observability, test quality, and developer experience, routinely fixing tests, linting, and enhancing logging to make systems more operable and debuggable. Alexandre has founded and shipped a full SaaS stack, pairing product-minded engineering with pragmatic architecture choices like hexagonal DDD and twelve-factor apps. Equally comfortable in Java and Python ecosystems, he brings a history of driving delivery pipelines and platform selections (Kubernetes, Prometheus, Grafana, Istio) that scale teams as well as systems. A practical tinkerer, he often surfaces obscure operational issues—such as subtle SNMP MAC parsing and metadata collection bugs—turning them into long-term stability wins.
