The problem FINANCE TRACKER solves
Most people suffer from "Financial Avoidance"—the habit of ignoring bank statements because they are overwhelming and boring. Standard banking apps provide a long list of transactions, but they fail to give a "bird's-eye view" of financial health.
This project solves this by:
Turning Noise into Signal: It transforms thousands of raw, confusing transaction rows into clean, interactive Donut and Trend Charts.
Identifying Spending Leaks: Users can instantly see if "Subscription Creep" or "Dining Out" is cannibalizing their savings goals.
Predictive Awareness: Instead of just looking at the past, the visual dashboard helps users forecast their end-of-month balance, making it safer to make big purchase decisions.
Bridge to Literacy: It makes complex accounting concepts (like Cash Flow and Burn Rate) accessible to non-technical users through a Gamified UI.
Challenges I ran into
Data Sync & Re-rendering Initially, adding a single transaction caused the entire dashboard to re-render, creating a visible lag.
How I fixed it: I utilized React.useMemo and React.memo to memoize the expensive chart calculations. I also moved the data aggregation logic (grouping by category) to the Backend (SQL) so the frontend receives a small, pre-calculated JSON object rather than thousands of raw records.
