Developed the foundational SIA Web Application Foundation for the AI-Artisans/sia_it42s1 repository, focusing on establishing a robust project skeleton using CodeIgniter and PHP. The work centered on backend development, creating essential configuration files, controllers, models, and views to support a scalable MVC architecture. By setting up the core system components and initializing the repository with a consistent structure, the developer enabled rapid future feature development and streamlined deployment processes. No major bug fixes were addressed during this period, as the primary objective was to scaffold the application and lay the groundwork for efficient web development in subsequent project phases.
