Freelancing iOS / Android Developer
I am Rafael, 38. Professional developer for 15+ years. Mobile developer for 10 years. I started to code as kid on a C64.
I am doing apps for Android and iOS for 10 years, for startups, agencies and big companies.
Before the mobile hype I was a backend/web and desktop developer.
Projects and Skills
Currently mainly: Swift or Java, but it depends on the project.
In my spare time: C#/Unity and Kotlin, with a neck for shader programming.

Buzz words: RxSwift/ReactiveCocoa/RxJava, Dagger2/Cleanse, Android SDK/NDK, git/SVN/CVS, UIKit/Cocoa/CoreData, fastlane/Jenkins/Bamboo and Espresso/Mockito/XCTest, Scrum/Kanban/JIRA/Confluence.
In the past: Objective-C and C/C++, and before 2010 also ASP/ASP.NET/PHP/node.js, MySQL/SQL/T-SQL, js/jsQuery/HTML5/CSS, and ages ago even Pascal/Delphi/Visual Basic.
I've done a programming apprenticeship/Ausbildung 15+ years ago, sort of equivalent to B.Sc. I've also studied mathematics and computer science (with a scholarship) but I left for a tiny startup that has 10,000 employees today.
I was lead developer many times. I've also owned an app and a mobile gaming startup myself. The B2B app startup was valued $50M at some point. The mobile gaming startup was called "Minecraft contender" by The Guardian.
I am in general easy to work with and always there if necessary. I relax while coding. I like mobile, procedural generation and hackathons/jams. A Chaos Computer Club member.
