Shashank Roy developed foundational project documentation for the 4DVarNet reimplementation in JAX, focusing on project planning and cross-framework evaluation. Working within the Diff4Earth/ige-jaxathon-2025 repository, he authored a comprehensive Markdown document that outlined objectives, deliverables, and success metrics to guide the team’s efforts. His approach emphasized early alignment by defining measurable criteria for comparing JAX and PyTorch implementations, including accuracy, speed, and memory usage. Leveraging skills in documentation and project planning, Shashank established a single source of truth to streamline onboarding and collaboration. The work provided a structured roadmap but did not yet involve direct code contributions.

March 2025 focused on establishing the foundation for the 4DVarNet reimplementation in JAX. Delivered a project planning and metrics document to guide scope, milestones, and evaluation against PyTorch. This documentation enables early alignment across the Diff4Earth team and sets measurable success criteria for subsequent implementation work.
