PROFILE

Charlotte Felius

Worked on the duckdb/duckdb-aws repository to deliver a robust upgrade cycle and CI/CD improvements over two months. Focused on aligning the AWS extension and core dependencies to DuckDB 1.5, the work included submodule synchronization, version pinning, and explicit versioning in continuous integration workflows. Leveraging skills in YAML, Shell scripting, and CMake, the developer stabilized build and test infrastructure, resolved Minio-related test failures, and integrated an S3 test server for reliable validation. These enhancements ensured reproducible builds, improved release readiness, and reduced maintenance overhead, providing downstream users with early access to new features and more deterministic development workflows.
