I am an English developer, travelling Europe and have been writing code for iOS since the swirling mists of 2009. I am well versed with many essential iOS frameworks. • AVFoundation (Audio, Video and Still Image) The AVFoundation framework provides services for working with time-based audio- visual media. I use this framework to capture and encode, decode and edit media formats using advanced techniques to create custom solutions. • Foundation I use the Foundation framework to access the essential classes that define operating-system services to incorporate design patterns and mechanisms to make apps that are both robust and efficient. • UIKit I use the UIKit framework to access the crucial infrastructure needed to construct iOS apps. This framework provides the window and view architecture to manage an app’s user interface and event handling of user input, and the system interaction model.

    “Elliot is a rare find! Very skilled iOS app developer. He developed and tested my app even before i hire him, i have not met a developer like him and i have previously hired at least 5 other developers for various stuff. None like him. His working ethic is a rare find nowadays. If i were to launch a startup, he would on the top of my list for a technological co-founder. Highly recommended.”


iOS Developer

Aug 2009

I gained my experience in Object oriented programmer learning how to master Adobe Flash using ActionScript 3 and then in September 2009 I made the switch to Obj-C for iOS. At the time Obj-C ranked 57 in the TIOBE Index and today it is now ranked at top 3. This is great to have both come so far together.
