PROFILE
Brandon Dahler
Worked on stability and security improvements across AWS infrastructure tooling, focusing on core serialization and signing mechanisms. In the Tietew/aws-cdk repository, addressed a critical bug in cross-stack reference handling by ensuring NestedStack list values are correctly serialized, which preserved output integrity and reduced failures in multi-stack deployments. Later, contributed to aws/aws-sdk-java-v2 by modifying the AWS v4 signing process to exclude the X-Forwarded-For header, preventing signature mismatches for proxied requests and enhancing request reliability. These contributions demonstrated expertise in Java, TypeScript, AWS SDK, and CloudFormation, with a focus on robust infrastructure as code and secure network protocol implementation.

Sep 1, 2025September 2025: Delivered a critical security and reliability improvement to AWS v4 signing in the aws/aws-sdk-java-v2 by excluding the X-Forwarded-For header from signature calculation. This change fixes signature mismatches for requests routed through proxies, reducing failure rates and enhancing request integrity for clients behind proxies. The work is documented under issue #6369 and committed as 5011e5c5d0ef2bb6e9b31ce7529fce9f182b7bda, then merged into master.
