A full-stack web application prototype built during DeltaHacks IX (36-hour hackathon at McMaster University). Alloy connects banking functionality with social features — enabling users to manage finances collaboratively and transparently.
🗓️ Hackathon: DeltaHacks IX (Jan 2023)
🛠️ Stack: Java 19, Tomcat 8.5, MariaDB, Maven
- Create and manage personal bank accounts
- Perform transactions (debit/credit)
- Bank account objects stored and linked to users
- Store extended user details (address, gender, etc.)
- User profiles integrated with banking and social modules
- Secure session support (via Tomcat session handling)
- Centralized SQL connection via factory class
- User-backed login support (DB-auth implied)
- Users can create forum-style posts and comment
- Boards and categories supported for post grouping
- Split into logical packages: banking, posts, users
- Built with extensibility in mind using
libhyextendedutilities
