Hi, I'm Christopher

I'm a mobile app developer
I work with iOS and Android natively
...but I also dabble in Unity from time to time

Christopher

iOS and Android App developer at Christopher Vikner AB - Based in Skövde, Sweden

I am a passionate mobile app developer with almost a decade of working experience, with a five-year-long game programming education as a foundation. The first few years I worked as a consultant, helping businesses of varying sizes with their mobile applications. Currently I am self employed working as an freelance developer.

Skills

Swift

Using as main language for professional development on iOS, and the language I have used the most these past years.

Objective-C

Usually only used to convert to Swift, but the first years of my career everything was written in Objective-C on iOS.

Kotlin

The past few years I have been focusing on Android, where Kotlin has been the main programming language. I do have experience with JAVA as well though.

Huawei / Google Play / App Store

I have experience on all stores, but deploying and managing has primarily been done on App Store.

Git

Experienced with git-based development, primarily using GitHub, but I am no stranger to GitLab either.

Unity

By no means new to me, since I have dabbled in it on and off for the past 10 years. But the past year I have been more serious, and really focused on learning this platform for developing games.

C/C++

Know basic C/C++ programming. Used as the primary language when studing my M.S.E. Nothing I have used professionally though.

C#

Mainly used for programming in Unity, but also what I used for my masters thesis project.

JIRA + Confluence

The issue tracker, and documentation tool, I used primarily at Sleep Cycle.
