Jan 1, 2025January 2025: Focused on reducing technical debt by removing AWS Amplify integration from the hack4impact-calpoly/habitat-for-humanity project. The change comments out Amplify configuration in App.tsx, effectively disabling Amplify authentication and backend services to simplify the code path and prepare for migration to an alternative authentication/backend stack. Result: cleaner build, reduced maintenance burden, and clearer roadmap for future integration work.
