Multiplatform app for developers meetup.
I love to attend developer meetups here in São Paulo capital, you probably can meet me in one of these.
The one which I most visit is the GDG-SP, the Google Developers Group of São Paulo, so I wanted to build an app to make networking easier between the participants, send new meetup notifications, make raffles, etc. Then I developed the GDG-SP app.
I have decided to use a lot of my knowledge to build the GDG-SP app, this is why there are Android in native Java, Windows Universal Platform in native C# and Xamarin.Forms versions for iOS, Windows Phone 8.1 and Windows 8.1. There are other Xamarin.Forms projects versions in UWP and Android, just in case someone may want to use it in lectures. It’s back-end I have made in object oriented PHP 7 with MySQL.
I also build a .NET 4.5 desktop program which generates a database of all people who confirmed their presence in an event, based on the Meetup events API. The apps generate a QR Code over the user’s login Meetup ID, then the program reads this QR throughout the webcam and identifies the member, generating a report containing the time every person arrived and people who missed.
Since I like to help new developers, all of this project is open source and available on my GitHub, whoever wants to study the code or even make versions of it to other meetups is able to.

Applications for blogs.
The BlogApps are general applications I have made from a common template I developed. From the website I make the application changing name and icon, but they usually become just equal to one another.
There are BlogApps versions I call lite, which is an icon that opens the whole site with links on the side of it, but it’s usually are very criticised for being so simple. The Full version is integrated to the OS which is made for, including it’s interface, Dropando Ideias for Android and Zelda.com.br for Windows 10 are full versions examples, these two versions also has new posts push notifications.
If it is in the customer’s interest, I also build a Google Chrome Extension using the same app interface including push notifications of new posts. I have been doing these extensions since a time which it wasn’t common for a site to have push notifications hahaha. These BlogApp versions are a freelancer thing, so if you want one of these to your blog or website just get in touch with me through the lateral menu over there 🙂
Application developed for my public High School.
RebuApp was an application that I developed in the middle 2014, I was 17 years old by that time. This app only was possible because the DroiDéx project, which gave me enough Android development experience to make it, together with my previous front-end, and the PHP and MySQL course that I was studying in that time.
The application idea was to have the time and agenda of all classrooms, for this the classroom spokesman would have a login and password, and the school coordinator (and I as application administrator) would have a special login in which could add new spokesmen, so whenever he had something new in the room of the agenda, the spokesman would add the event in the application and thus appeared in the application of other students who chose that classroom.
Since I had no back-end knowledge in the beginning of it’s developing, I used alternative stuff: Tumblr was the host for my pages, because HTML pages was possible in it, and JotForm, in an another Tumblr protected with a password in it, laos the spokesmen would get in touch with me through this so the I would add new stuff to the agendas. But in the later month I learned PHP and hat it all automated.
Taking advantage of an Word document containing all the library books, I also put in the database all of the school’s library books, making possible book searching from the app.
I spent all my 2014 December vacations trying to make native apps (until then, I only made WebView apps, you can see it’s source code on my GitHub), when I got it, launched the current Play Store RebuaApp version, with a lot of new features, the school that I made the app was an integral high school, the app until that day was messages from clubs (a class with groups of students with same interests) and electives (the same thing as a club but with a teacher mentoring), the spokesman could even send push notifications to the students when using their login. There were images from the school posters, the school canteen’s menu also was available in the app, official announcements, links of the school’s blog and newspaper also were available. The app has too an integrated dictionary and a notepad. I also build a web version of the app using Polymer (when it still was beta) to use the Material Design of the Android version and for the users of another system could access it. Last, but not least, everything of the app is into a Google Chrome Extension, including push notifications.
The idea was great (I was impressed remembering the features of it writing here hahaha), even more because was a public school, to spread I glued posts around the school, at strategic points, like next to the snack line:
It seemed an awesome idea, which had everything to succeed, and it really did for some time. But it depended on people who would update it by their own will to work, I even added a function allowing others than the spokesmen to feed the app, but in vain. It has been totally forgotten by the students. The app remains on the Play Store just to show it to people.
Pokédex app for Android
DroiDéx was my first Android application, I have decided to develop it when i was 17 years old just when I realized that the DéxDroid developer have had given up of it’s development. So just as I found out it was open source I started out to continue it’s development.
I tryed to discover how to add new pokémon, I discovered that has a database, until this I never had play with a database but I discovered how to add new info, and I added the pokémon added until that date, so some days after I launched the first DroiDéx version, already understanding the most part of the code and I’ve been adding new features that I wanted, like change the application color according to the selected pokémon, open the pokémon page in Bulbapedia and anothers pokémon site, and my favorite new feature, which was add any pokémon widgets to the homescreen, I have added also the pokémon sounds and animated gifts of it all, finally, was features that I dreamed in anothers pokédex apps, but no one added in their apps, so I added in my app by myself hahaha.
But unfortunately happened to me the same thing of the previous developer, like the most pokédex apps, it was suspended from Google Play Store by DMCA, it means using Pokémon names and images without permission, so I got discouraged and stopped it development, you still can download it’s apk clicking here.
I took this opportunity to see how many downloads has the last DroiDéx version actually, it is because isn’t in the Play Store and I’m not doing any divulgation, think if I do that hahaha, in the Play Store it has a little more than 1000 downloads and 150 five starts in one week.
Google Chrome extension for a humoristic wiki
in the lan house, because I didn’t have computer at this time… searching about everything that I wanted to add in it, I didn’t understand anything about programming logic, I just saw the source code of a finished Chrome extension and I tryed to learn it in some way, in some moment I learned how that code works.
You can even see how was the source code of the first beta version in my GitHub (I just understood for what GitHub was for and learn play in it when the DescicloApp was in version 3, I was 15 years old, because of that the date isn’t correct).
As I didn’t have a computer and an international credit card to open a Chrome Web Store developer account, I used alternative methods to divulge and update my Chrome extension projects, I needed a service that keeps the .crx (Chrome extension file) at the end of the download URL to the Google Chrome understand that is an extension and directly install it, it was then that I found the already discontinued Google Code, I had made XML files to have automatic updates outside the Web Store hahaha.
Nowadays I think that methods don’t work anymore because the Google Chrome reforced a lot the security preventing installation of extensions outside the Web Store, but when I was 17 years old I knew about the pre-paid credit cards, from there I finally opened my Chrome Web Store developer account (and the Google Play developer account, because I was starting to build Android apps at this time) and you can find it there.
Between that time I also wanted to build extensions to other browsers, so I build the DescicloApp for Opera (including at time that it wasn’t a disguised Google Chrome) and Firefox (they didn’t want to accept new version so I stopped the development of new Firefox versions).
DescicloApp was developed during more or less 3 years (I stopped to access the website, is a portuguese version of Uncyclopedia), you can see all the it’s features and images clicking here, for someone who started web development from 0 and don’t have any course at these time, it looks great.
My first projects was very simple things, like Google Chrome themes and one click extensions, and Google Toolbar buttons when I was 13 years old.
As I learn practically everything seeing other people’s code (StackOverflow <3), I love to publish projects on GitHub thinking that someone will see that code and learn something, some other projects that I build are:
Quiz Programming – I earn a presential course from Microsoft about UWP (Windows 10) apps development, where I learn C#, to pass to the second level of the course was necessary build an UWP Quiz application and publish it in the Windows Store.
AppTest – Application with a simple objective, help new programmers to build Android apps, seeing the it’s code you can understand all the structure of an Android application project, and it’s super commented (in portuguese, in that time I do trust in my english hahaha) to be easy to understand how to add a click event to a button and create new application screens.
Alefe Ultimate Programmer – I love Naruto Ultimate Ninja Storm game series, why not have a game like this but with programmers? hahaha, I started it recently, in may 2016, without any knowledge about game development, I am like to going back to my roots just copying code and trying to understand how it works like I did in the beginning of DescicloApp. If you like Naruto and programming, if you think a time you can see that exists a rivality story that is the same as the technology companies, in this game for example, Madara and Hashirama are Bill Gates and Steve Jobs, and the chakra mother, Kaguya, will be the programming mother, Ada Lovelace.
