Ponto Fácil
Time tracking for nannies and caregivers who work for several families: clock in, close the month and charge via Pix.
- Django
- PostgreSQL
- xhtml2pdf
- qrcode
- whitenoise
The problem
Caregivers who work in several homes track hours on paper or in a notes app, and at month end have to add everything up, split it per family and charge each one. That's where hours get lost.
What I built
A mobile app with one button to clock in, a schedule to plan the week and a report that comes out with each family's total and a Pix QR code to pay.
- Clock-in per family with hourly rate, transport and expenses
- Schedule with recurring visits
- Monthly PDF report per family
- Pix payment QR codes generated in-house (BR Code)
Technical decisions
- Each entry stores the hourly rate applied, so changing a family's rate never rewrites closed months.
- The Pix payload (EMV/BR Code standard, with CRC16) is built in-house, with no bank API dependency.
- Recurring visits share a series ID, so you can delete one day or the whole series.
- Expense receipts are attached to the clock-in entry itself.
- One-handed interface: the running clock-in sits on top and navigation lives in the bottom bar.
