Latest Projects

The 72 Names Of God ios App

The perfect guide to study and meditate on these wonderful keys to expand your awareness and dive deeply into your inner self

The 72 Names Of God
New

This is the first personal project ios app I publish to App store.
The app uses the device language settings in Portuguese (EN) or English (US), if the language is other the default is English.
I developed this application because there is no Portuguese version of this literature in free applications and I participate in Kabbalah study groups that asked me to make this application.
That's why it's free with the ability to watch advertisements by manually clicking a "Watch an Ads" button (To help me with maintenance costs and cloud hosting of remote language files available).

There are a number of technologies involved in this application, Firebase events and Analytics, CI / CD automations and tests, CoreData, Remote Sync, and there is a multilanguage app for complete offline use. It works on iPod, iPhone and Ipad devices.
The application works completely offline after installation as it installs a local list and my idea is that the Kabbalistic community around the world can collaborate on translations that are in remotely hosted json files. Available languages ​​are on the language settings screen for the name lists.

There is a Hot Site to explain how this app works. Take a look.

Not available anymore at Apple Store. I Can't pay $100,00 every year.

Insonic - my music main solo project Free to listen on some audio players

This is my personal music project.
Not so far from computers, but focused on music and its processes of recording, mixing, mastering and stocking alongside analog and digital synthesizers, electronic drums and some string instruments, blowing and percussion, which were my companions before marrying and forming a family. I was able to record 2 albums, sell songs in soap operas, publish solo songs and in partnerships with great names of the electronic scene in international collections, and to play live in several parties all over Brazil. I really hope one day to have more time to be able to produce and play again ...
