I started my iOS Developer career in 2013 making a new feature for an online banking application. It was the time of iOS 4+ support and Manual Memory Management. Since that time I created dozens of applications and posted them to AppStore. These were social networks, games, entertainment and business apps. 
Also, I was the first developer in the company(Yalantis) who started to learn Swift(since 1.1) and then I wrote the article and made series of presentations to other team members to expose a wonderful world of Swift to them.

During my career, I faced the challenges of optimizing high-load applications. For example, we had an app that needed to load thousands of records from the server and show them as complex cells in the list. It had to load history and search for new records simultaneously updating the list in real-time with reactive binding to a database. It was a hell of multi-threading and UI optimizations but I did it.
Challenging tasks, influence on product, a chance to make something beautiful
