More than 15 apps I worked on, 7 of them were published on Appstore, 3 were published via Enterprise license.
Tech leading experience.
Examples of projects:
Messengers, E-commerce, Augmented reality and Enterprise projects for analytics.
Example of non-trivial tasks I worked on:
- Tasks with OpenGL(for example, it was necessary to optimize the loading of models, for this I had to write a bridge in C, as a result, loading of models decreased by 10 times);
- Tasks with Metal(used metal for mixing videos using AVVideoComposition)
- Writing your own protocol based on TCP (it was needed for a Real-time application and therefore various techniques were used to optimize sending and receiving packets (TCP delayed acknowledgment))
- An application for recognizing certain objects (before launch of CoreML) based on OpenCV;
- Simple application for deleting background using CoreML
- Applications with Augmented Reality(with ARKit and Vuforia);
- Writing custom CollectionViewLayouts with complex animations and transitions.
Decreased tests writing time by 30% by adding code generation for mocks and boilerplate tests
Fixed Real-time video bugs by moving code from UIKit to Metal shader
