PROFILE
Romain Marcadier
Romain Marcadier contributed to the DataDog/datadog-lambda-extension repository by porting the Serverless AppSec Protection Processor from Go to Rust, integrating it into proxy and trace processing to enhance API security and prepare for Go agent deprecation. He improved performance and reliability by migrating to Tokio-based asynchronous locking, resolving runtime dependencies, and optimizing startup with static linking. Romain also focused on observability, reducing log noise and improving error handling for clearer operational insights. His work in Rust and Go emphasized robust backend development, delivering features like null-safe API Gateway response deserialization and targeted logging improvements to support maintainable, production-grade serverless systems.
