Service Description

Extensive experience working with C#, C++. Java, Objective-C while also being responsible for the backend implementation in C# and Ruby On Rails with embedded HTML and CSS.

Version management tools experience with SVN, Github, TFS and SVN, alongside a RUP or SCRUM development process.

When working on projects, I always make sure an issue tracking system is in place to give a good history and overview of the project at any given time. If there is no existing one available for the project, I will supply one for milestone-overview, task tracking, hour estimations and bug reports.

During development the app will also be made available at any time for testing by the customer, to make sure the project is on the right track as well as giving visual feedback of the progress made.
