_Better to learn something is to start explaining things._ I started with answering questions on Stackoverflow some time ago, all my answers lead to communication with topic's starter and end up with posting a working code example. I want to help, because I learn something new, because today is hard to find people out there at some meet-ups and find out what interesting projects they are working on. With over 12 years of professional experience, I am a senior iOS developer passionate about creating engaging, user-friendly, and reliable iOS apps, using SwiftUI, RxSwift, and Auto Layout as my core technologies. I have contributed to multiple iOS apps and publications, including the LeoVegas apps, Car Navigation: Maps & GPS, Onlia Sense, and the Klima and BorrowNotBuy prototypes. I have also won several honors at hackathons and startup weekends, and written articles on IT-industry trends and innovations. I enjoy mentoring and conducting workshops for my colleagues, and following the Apple Human Interface Guidelines to deliver the best user experience.
