PROFILE
David J. Schodt
Worked on the lanl/Yoke repository, delivering end-to-end enhancements for deep learning training workflows and dataset management. Over eight months, built and refactored Python-based CLI utilities, implemented PyTorch Lightning harnesses, and introduced HDF5 dataset caching to improve data throughput and experiment reproducibility. Developed features such as low-resolution training, dynamic sequence generation, and configurable sampling, while strengthening code organization, test coverage, and CI/CD reliability. Addressed backend bugs and improved string processing robustness, ensuring stable data handling. Leveraged skills in Python, PyTorch, and shell scripting to create scalable, maintainable pipelines that support efficient experimentation and onboarding for machine learning projects.
