About me

iOS Developer with 6+ years of development experience. Since 2020 I have focused on Swift and SwiftUI and built my own products from scratch. I cover the whole cycle: product concept, UI/UX, architecture, development, backend integration, testing and App Store release. I work with instant messaging, audio and video calling, and Supabase and Firebase backends. I also have my own Apple Developer account.
