Building and Hardening My Spend Tracker

I built a personal spend tracker to answer one question quickly: where is my money actually going each month? The app ingests ASB statements, categorises transactions, tracks budgets, and runs a local AI assistant for summaries and cutback advice.

Over time it stopped being just a finance tool and became a proper systems project. Once I decided to put it on the public internet, the focus shifted from “does it work?” to “can I trust it when I am not watching it?”
