Summary
🤩
RockstarWilliam F Godoy is a Senior Computer Scientist with nine years of experience building high-performance scientific software at Oak Ridge National Laboratory. He blends back-end C++ development for scalable finite element libraries with DevOps and CI expertise, having improved ADIOS2-based mesh I/O in MFEM and hardened GitHub Actions pipelines (including CUDA and clang-tidy) for QMCPACK. Comfortable working at the intersection of computational science and engineering, he focuses on robust, portable tooling that enables production-grade simulations on HPC systems. His contributions reveal both low-level data-schema design for mesh export and pragmatic automation to raise code quality and test coverage. Based in Oak Ridge, he brings a researcher’s attention to numerical data fidelity together with an engineer’s drive to make complex workflows reproducible and maintainable.

mfem/mfem
Mar 2020 - Oct 2020
Lightweight, general, scalable C++ library for finite element methods
Role in this project:Back-end Developer
Back-end DeveloperContributions:6 commits, 3 PRs, 45 pushes in 7 months
Contributions summary:William primarily contributed to the `adios2stream` class within the MFEM library, focusing on integrating the ADIOS2 I/O library for saving mesh data. Their work involved defining and utilizing ADIOS2 variables and attributes to store mesh-related information such as element connectivity, node coordinates, and element attributes. These changes included updates to the VTK schema for improved compatibility and a format upgrade. They enhanced the interface by incorporating element attributes ("material") into the output, enabling more comprehensive data representation.
