🚀 Key Technical Innovations

📉 Smart Settle Algorithm

Our greedy optimization engine reduces complex group "webs of debt" into the minimum number of transactions. Ported from Java to TypeScript, it maintains the same high-performance logic with modern async patterns.

🛡️ End-to-End Type Safety

Using TypeScript across both the Frontend (React/Vite) and Backend (Express/Prisma), we ensure data integrity from the database layer all the way to the user's screen.

🍱 High-Aesthetics UI

• Premium UX: Built with React + Vite using Glassmorphic panels and a curated deep charcoal design system.
• Micro-animations: Smooth, interactive transitions powered by framer-motion.

🛠️ Tech Stack

• Frontend: React 19, Vite, TypeScript, Auth0 SDK, Framer Motion, Axios.
• Backend: Node.js, Express, TypeScript, Prisma ORM, Auth0 Resource Server.
