Ilia Aleinikov

City of London, GBiOS Developer

I’ve contributed to both outsourcing and product-based projects, working in teams of 2-40 members across remote and on-site setups. I manage full app lifecycles—from idea to release, maintenance—ensuring clean architecture, crash-free performance, test coverage, CI/CD, and analytics. Skilled in Swift, UIKit, SwiftUI, Combine, async/await, CoreData, multithreading, offline-first apps, and scalable architecture. Proficient in functional reactive programming and declarative UI. I mentor junior developers, lead onboarding, and support team growth. Passionate about Apple’s innovations in AI and AR, I stay up to date with WWDC trends and new tech. For 2+ years, I’ve been building my personal brand by teaching iOS development at university, sharing real-world experience with students.
