5 / 6Game
Cascade: Colour Sorting
A calm colour-sorting puzzle where you move one token at a time and every move counts.
- Role
- Developer.
- Decision
- A solver solves every level before it ships, and its optimal move count becomes the par for that level. Three stars means matching the solver.
- Result
- On the App Store. Plays offline, with no ads, no in-app purchases and no sign-up.
6 / 6Game
Helicopter Game: Cave Edition
An endless cave flight with a single control: drag to steer, release to hold your line.
- Role
- Developer.
- Decision
- Reward risk. Grazing a rock without touching it banks a scoring multiplier, so flying close scores more than playing it safe.
- Result
- On the App Store.
How Expenzez works behind the scenes
Transactions come in three ways, with no bank connection needed. The app talks to a small set of serverless functions on AWS, and transactions are saved to a database.
Statement PDF
Pick a bank statement PDF. The app uploads it, shows what was found, and waits for you to confirm.
CSV file
Pick a CSV export from your bank and import its rows as transactions.
Manual entry
Add a single transaction by hand.
Mobile app
A React Native app for iOS and Android. It collects the three kinds of import and calls the API.
HTTP API
One API in front of the backend. Each action in the app maps to a route that calls one function.
Serverless functions
Small functions with one job each, such as reading a statement PDF, importing a CSV, or saving a transaction.
Temporary storage
Holds an uploaded PDF just long enough for a function to read it. The app sends the file here directly.
NoSQL data store
Transactions, accounts and the list of imported statements are saved in NoSQL tables.
