Matthew Geng contributed to the DataDog/datadog-agent repository by developing and enhancing core agent features focused on process collection, service discovery, and container observability. He implemented robust telemetry and logging, refactored process metadata collection for containerized environments, and improved reliability across Linux and Windows platforms. Using Go, Protocol Buffers, and YAML, Matthew delivered features such as container-process correlation, language-aware workload metadata, and configurable process collection intervals. He also addressed critical bugs affecting ECS Fargate and process monitoring, stabilized CI pipelines, and maintained high code quality through targeted refactoring and comprehensive testing, demonstrating depth in backend and cloud infrastructure engineering.

For 2025-12, DataDog/datadog-agent focused on stabilizing ECS Fargate container status reporting. Delivered a critical bug fix in the core agent that ensures the container status is correctly assigned during the collection cycle, addressing unknown statuses observed after agent version 7.65 and improving overall container visibility and reliability for ECS Fargate workloads.
