PROFILE
Brandon Dahler
Brandon Dahler focused on stability and security improvements across core AWS infrastructure projects. In the Tietew/aws-cdk repository, he enhanced cross-stack reference handling by fixing serialization of NestedStack list values, ensuring output integrity and reducing deployment failures in multi-stack environments. Later, in aws/aws-sdk-java-v2, Brandon addressed a security issue by modifying AWS v4 signing to exclude the X-Forwarded-For header, preventing signature mismatches for proxied requests and improving reliability for downstream services. His work demonstrated deep understanding of Java, TypeScript, and AWS SDK internals, delivering targeted bug fixes that strengthened infrastructure as code and secure network protocol implementations.

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.
