_01. Case Study
SpendWise
SpendWise is a full-stack budgeting app I built to solve my own problem of losing track of daily spending. It lets users log transactions by category, set monthly budgets, and visualise spending patterns over time. Firebase handles auth and real-time sync, so data updates instantly across devices.
Full Stack
The Problem
I kept overspending without realising it until end of month. Spreadsheets were too slow and existing apps felt bloated or needed a subscription.
The Solution
Built a lightweight web app with a fast transaction input flow, auto-categorisation, and a monthly overview dashboard. Firebase Realtime Database keeps it synced instantly.
The Result
Used it myself daily for 6+ months. Helped me cut unnecessary spending by tracking where money was actually going. Shared with friends who started using it too.
