PROFILE
Théo Putegnat
Theo Putegnat contributed to the DataDog/datadog-agent repository by developing and enhancing security monitoring, observability, and remediation features over a nine-month period. He engineered syscall and session tracking, network event capture, and remediation workflows using Go, C, and eBPF, focusing on Linux kernel integration and cloud security. Theo refactored core event processing logic for maintainability, improved test reliability, and introduced real-time event handling to reduce operational delays. His work addressed both feature delivery and bug resolution, emphasizing code hygiene, concurrency safety, and documentation. These efforts resulted in more reliable security telemetry, safer remediation operations, and improved CI stability for production deployments.

Feb 1, 2026February 2026 monthly summary for DataDog/datadog-agent focusing on reliability and correctness of remediation workflows. Key updates include stability improvements to the Remediation Status Report and Actions by addressing three related bugs: (1) proper handling of cgroup scope within remediation reporting, (2) preventing agent panics when executing certain remediation action orders, and (3) correcting the key computation for remediation actions. These fixes reduce downtime risk, prevent incorrect remediation mappings, and improve overall trust in remediation results. The work demonstrates strong debugging, code hygiene, and safety in production-critical paths, with a clear business impact: more reliable remediation operations and safer deployments. Technologies/skills demonstrated include Go/Agent code contributions, Linux cgroups handling, concurrency-safety fixes, and thorough triage and validation under CI.”,
