A savings account inside the supermarket checkout lane, with every transaction tied to the store that took it so it lands in that store's end-of-day reconciliation, and a specification written to close the holes in the client's own.

A fixed-income desk's daily trading tools rebuilt off forty hand-maintained files onto the Bloomberg feed, and a years-old display fault nobody could solve traced to the vendor's own software. Fourteen years on the desk.
The desk priced US and European treasuries, bills, futures, deposits, swaps and OIS live off a Bloomberg terminal, using a desktop application fed by around forty flat files maintained by hand next to the program. It also had a display fault, years old, that nobody had been able to diagnose.
Rewrote the main application to pull from the Bloomberg API directly instead of the hand-maintained files, added futures screens with automatic contract rollover, and produced a full map of every Bloomberg field to the code that uses it, so the desk's tools were documented for the first time.
Found the notorious 'mouse flicker' fault inside the market-data vendor's own .NET wrapper, which was leaking memory, and not in the desk's application at all. Fourteen years on the desk.
