About this gig

Have an idea for an app, or a manual process you want to automate? I build custom Android apps and Windows programs around how your business actually works, with your data backed up to the cloud.


What you get:

- A working, installable app, not just a mockup

- Clean, simple screens made for daily use

- Cloud backup of your data

- Support in English and Spanish


What I build: sales and POS apps, bookings and appointments, inventory, customer management, accounting tools, order tracking and internal business programs.


I also build and sell my own business software (ContaSys and EasyPOS), so I know how to make apps that non-technical people can use every day.


How it works:

1. Tell me what you need

2. I send you a working prototype

3. We refine it with your feedback

4. You receive the final app


Message me before ordering with a short description of your idea and I will tell you which package fits.
