PROFILE
Jeremy Besson
Jeremy Besson contributed to the elastic/apm-agent-dotnet repository, focusing on enhancing reliability, diagnostics, and integration for the .NET APM agent. Over six months, he delivered features such as TLS 1.3 and HTTP proxy support, improved distributed tracing, and added runtime diagnostics by logging target framework monikers. Jeremy addressed critical bugs, including NullReferenceExceptions and request body capture issues, by refining error handling and context management in C# and ASP.NET Core. He stabilized CI pipelines using GitHub Actions and Terraform, expanded compatibility with Confluent Kafka 2.x, and maintained robust documentation. His work demonstrated depth in backend development, instrumentation, and configuration management.

Jul 1, 2025Monthly summary for 2025-07 focusing on elastic/apm-agent-dotnet. The month centered on hardening ASP.NET Core diagnostics by improving error handling, context initialization, and monitoring data quality. Key features delivered: improvements to error handling robustness and context initialization to ensure baggage can be captured and attached to Error objects, with clear separation of handled vs unhandled exceptions for accurate monitoring. Major bugs fixed: prevented potential NullReferenceException when the 'transaction' is null during Error object initialization; enhanced monitoring accuracy by explicitly marking handled exceptions. Overall impact and accomplishments: increased reliability of the APM agent in ASP.NET Core scenarios, reduced risk of silent failures, and improved data accuracy for alerts and troubleshooting. Technologies/skills demonstrated: C#, ASP.NET Core diagnostics, advanced exception handling, baggage/context management, code refactoring, and commit-level traceability.
