Problem

- Users need a **single place** to send money, pay bills, and do mobile recharge instead of using multiple apps or sites. - The product needed **secure auth** (login, signup, 2FA, OTP) and a **reliable backend** without building custom servers from scratch. - The app had to work on **mobile and desktop** with a clear dashboard and navigation. - The UI had to feel **modern and trustworthy** (fintech-grade) with consistent theming and no default browser look (e.g. scrollbars, layout).

- **Unified dashboard** with one layout: sticky sidebar (100vh), main content scroll only, and quick actions for Send Money, Pay a Bill, and Mobile Recharge. - **AWS Amplify** for auth (Cognito), API (AppSync), and database (DynamoDB) to ship faster and keep security and scalability handled by AWS. - **Next.js + React** for SSR/SSG, code splitting, and reusable components; **MUI** for responsive layout, drawer on mobile, and consistent components. - **Themed UX**: custom scrollbar (teal on dark), active menu state, dark theme (#1AE7E0 accent), and i18n for multiple languages. - **Full auth flow**: login, signup, 2FA, OTP verification, forgot password, and new password with Amplify UI and custom screens.

Result

**One app** for transfers, bill pay, and recharge with a single login and clear navigation. - **Scalable, secure backend** via Cognito, AppSync, and DynamoDB without managing servers. - **Responsive experience** with sticky sidebar on desktop and drawer on mobile; only main content scrolls. - **Polished, on-brand UI** with custom scrollbars, active states, and dark theme suitable for a portfolio or demo. - **Reusable foundation** (layout, auth, product flows) that can be extended with more features or connected to real payment APIs.
