Senior🎓
Top SchoolSarah Weissman is a Principal Software Engineer in Baltimore with 14 years of experience building reliable, test-driven systems for science and defense organizations. At the Space Telescope Science Institute she leads engineering efforts that bridge astronomy software needs and robust production practices, bringing deep expertise in QA and test automation. Her background as a mathematician and applied ontologist with the DoD and HIGHFLEET gives her a rare blend of formal rigor, information science perspective (MLIS), and practical software design. An active contributor to high-profile open-source projects like Astropy—where she strengthened VOTable validation tests—she focuses on improving correctness and reproducibility in scientific tooling. Notably, she prefers non-cleared roles and excels at turning rigorous validation requirements into maintainable test suites and resilient systems.

Contributions summary:Sarah contributed to the `astropy/astropy` repository by writing and modifying tests for the `astropy.io.votable` module. Their commits focused on ensuring the correct output of the `validate` function, including testing various scenarios with valid and invalid VOTable files and different output options. The user's work involved adding new tests, fixing a function name, and making the testing suite more comprehensive. This improves the robustness and reliability of the VOTable validation within the astronomy library.
