Hi! I’m a software engineer working for the last six years with java development. I already worked with multiplayer online games, I also worked in a legal platform that manage millions of juridical processes. I had to deal with legacy systems, improve, fix old bugs, and automate the buildings (maven, Bamboo/Jenkins). I already manage many servers too. And I know a lit bit of frontend (javascript, css), but I prefer work in the backend.
I’m looking for some job in Europe, but I also would be interesting in some others places if I can get a working VISA.
SMS was expensive in Brazil before Whatsapp. Furthermore, it took more than half an hour to a SMS arrive in most of the time, sometime more than a day.
A lot of people don't pay cellular data plan and use whatsapp on wifi.
Whatsapp arrived as a free service on android. The app was really fast even in slow smartphone. And uses your cellphone number as id, so it was really easy to know whom was using.
I made a lot of people to use whatapp, because it show if you had send the message and if the other person has read. A problem I had with SMS.
And others messengers? (IMHO)
* iMessage is restrict on iPhone and Android dominate market share in Brazil.
* Facebook Message was only put in a different app latter in the game. And Facebook App is a bloatware, so it is practically unused on slow smartphones.
* Skype app was slow and it didn't use your cellphone number, so I had to ask personally.
* Gtalk didn't synchronized messages correctly and I never saw someone outside tech people using it. (Hangout fix the first problem).
A few others tried: Kik, WeChat, zapzap (Brazilian messenger). But none has the mass use. Now days, even my gramma is using Whatapp, so it will be difficult to change.
Telegram is increasing the number of people. I had a lot of friends sign up during this blockage.
The only option enable for me is "system data file and security updates".
BTW, if someone doesn't want to use terminal. It's possible to control all App Store downloads/install behavior on "System Preferences" > "App Store".
