PROFILE
Stefanie Reuter
Developed and maintained data integrity and metadata management tools across multiple scientific computing repositories. Delivered the fdb-compare command-line tool in the ecmwf/fdb repository, enabling reproducible cross-instance data integrity checks with a modular architecture that separates MARS and GRIB logic for maintainability. Addressed interoperability in FESOM/fesom2 by aligning metadata keys for compatibility with the multio library, ensuring stable data and mesh processing in Fortran-based workflows. Fixed HEALPix grid encoding in ecmwf/metkit, resolving metadata interpretation issues for grid-based operations. Work demonstrated proficiency in C++, Fortran, and Python, with a focus on CLI development, library integration, and robust data comparison.

Aug 1, 2025Monthly summary for 2025-08 focused on interoperability and data integrity improvements in FESOM/fesom2. Delivered a critical bug fix to align global size metadata with the multio library v2.6.0, preventing incorrect size reporting and stabilizing data/mesh processing workflows. The change preserves reliable simulations and downstream data pipelines while maintaining compatibility with external libraries.

Jun 1, 2024June 2024 — Delivered the FDB Data Integrity Comparison CLI (fdb-compare) for cross-instance integrity checks between two FDB databases in the ecmwf/fdb repository. The tool enables targeted, reproducible comparisons across three scopes (MARS keys, header-only, full data) and three GRIB methods (key-by-key, hash, bit-identical), significantly simplifying data quality verification across environments and migrations. The implementation emphasizes a clean separation between MARS-level and GRIB-level logic, improving maintainability and future extensibility. Co-authored by team members; implemented in commit 69047b7eafe037bfa67d3d4a316184da2f1321df.
