• The core workflows of the Windows Engineering System represent a unique problem space due to both the massive scale as well as the diversity of services and technologies required for reliable delivery. I designed and built a service platform and telemetry methodology that enables distributed tracing and measurement experiences that are able to scale and adapt to the constantly evolving workflows we deliver. Using this system, we have empowered service owners to move from managing multiple isolated data silos to leveraging a unified data infrastructure of pre-correlated, contextually rich, reliably structured data.
