Willgnner Santos developed the initial project structure for the Willgnner-Santos/Fatesg-IA-2 repository, focusing on organizing code and data workflows to support scalable, data-driven development. Using Markdown for documentation and emphasizing project structure organization, Willgnner created top-level directories for Big-Data, Banco-NoSQL, and PI, each with dedicated README files to guide contributors. Visual assets were added under Big-Data to clarify data concepts, supporting easier onboarding and collaboration for data teams. While the work was foundational and limited to one feature, it established a clear, maintainable architecture that enables future development and improves clarity across the project’s data-focused components.
