Jillian Crossley

Jillian Chen developed a recursive listing feature for the S3 Blobstore client in the apple/foundationdb repository, enabling users to enumerate all objects within a bucket using a new --recursive flag on the command line. She migrated the S3 integration to use the ListObjectsV2 API, improving pagination reliability for large datasets. Working in C++ and focusing on command line interface development, error handling, and S3 API integration, Jillian also addressed a heap-use-after-free issue to enhance stability during object listings. Her work improved data discovery and operational reliability, reducing maintenance overhead and making S3-backed blob storage more usable for operators.
