PERSONAL SOFTWARE · FINANCE

Your money, a little easier to understand.

I build and maintain Piggy, a personal finance app that turns Google Sheets entries into a clearer view of budgets, cash forecasts, and investment progress.

It brings together two things I enjoy: building useful software and understanding how we make decisions about money.

Adjust the home price, mortgage, rent, and investment assumptions to explore different scenarios.
