About
During my job experience as an iOS Developer I have been facing lots of technical challenges and issues: - projects, that started from scratch, provided development till release, configured continuous integration, analytics, etc.; - legacy code, bug fix and refactoring, implemented new features; - communicated a lot with different development departments regarding features implementation; - regularly communicated with a customer directly; - worked in iOS team on a project, as well as by myself; - regularly participated in code review sessions; - successfully implemented new language features such as async/await, and frameworks such as SwiftUI in different projects; - worked on several projects at the same time; - worked on a project with 1M+ registered users for a past year, so I am familiar with specifics of a large product; And now I’m looking for new opportunities as a part of a new team, and I’m excited to talk more about it during interview.
