Private personal-finance dashboard - Excel ritual replacement

Completed Next.js 15TypeScriptSupabaseZodTailwind

Mission brief

Problem

Spending lived in a 14-sheet expense tracker while balance and income lived in a separate overview workbook. Every month meant pasting, retyping, and reading results by eye.

Role

Solo builder across product framing, data model, parser behavior, responsive UI, and the interactive deck export that presents the system as a self-contained case study.

Outcome

A private web dashboard where raw transactions, bank balance, and income are stored once; KPIs, breakdowns, trends, and projections are computed live so figures do not go stale.
