Crossbox: Django webapp with Stripe payments that scaled a gym business from 30 users up to 500 users in matter of months automating all the manual work of handling the group sessions, the reservations, the payments, etc. Now the bottleneck of the growth of this business is the physical space, is not the technology anymore. Once the gym owner rents a bigger space this app will allow him to scale without modifications.

Balaland: PyGame 2D shooter game that tries to emulate what would be to play a 3D 1st person shooter in case of being played from a 2D view like in GTA2. Balaland respects the angle of view like if the camera was set from a 3D 1st person point of view, that means if you don't peak a corner you will see black everything that's behind a wall. Using ray casting to achieve that. Also some basic AI for the enemies to make them a bit competitive. Still work in progress.
