Unicash
A complete personal finance ecosystem featuring a user dashboard for tracking income/expenses and a dedicated admin console for system management.
Product UI Preview
Project Overview
Unicash is a robust full-stack web application designed for personal finance tracking. Unlike simple scripts, this is a complete ecosystem split into three distinct applications: a REST API backend, a client-facing dashboard, and a separate admin administration portal. Users can securely log in via OTP/2FA to track income, expenses, and savings, while visualizing their financial health through interactive analytics and trend charts.

Challenges & Solutions
Problem / SolutionChallenge
A major technical challenge was architecting the security and maintenance flow across three separate apps.
Solution
I implemented a robust middleware system in the Node.js API that handles typed JWTs (access, registration, 2FA) and enforces a global 'Maintenance Mode' that blocks non-admin API traffic while signaling the React client to display a maintenance overlay.
