Spreadsheets annoyed him, so he built the tool he actually wanted — a full-stack net-worth app.

The problem

I wanted to actually see my money (accounts, values, trend over time) in one place, updated the way I think about it. A spreadsheet did the job badly, so I built the real thing.

What I built

A passcode-protected net-worth web app: a Next.js front end, a Supabase database and auth behind it, and Recharts for the visualizations. Real accounts, real data-modeling, real deployment, not a to-do-list demo.

The net-worth tracker app open to its passcode lock screen, a numeric keypad. No financial data is shown. — EXHIBIT E-11 · The net-worth tracker: a Next.js + Supabase app I built. Passcode screen only; the data stays private.

The numbers

The stat that matters here isn't a dollar figure (that part stays private); it's that it's a real deployed, authenticated, data-driven app — accounts, values, and trend over time, running in production.

What it taught me

How the pieces of a modern web app fit together end to end — front end, database, auth, deploy. Building something I actually use beats any tutorial project.
