Kanstantsin Klinau — IOS Engineer

iOS Software Developer with 5+ years of commercial experience building secure, scalable mobile applications in Web3 and logistics domains. I specialize in Swift, SwiftUI, UIKit, and Swift Concurrency (async/await), with strong experience designing modular architectures (MVVM, VIPER, MVP, Coordinators, TCA) that improve scalability, testability, and long-term maintainability. At Ultra Stellar, I played a key role in developing Web3 payment and wallet applications, integrating Web3 SDKs and implementing secure, reliable transaction flows. I contributed to building scalable mobile architecture, improving code modularity, and enhancing overall app stability. Also I worked on the logistics platform Radaro, helping evolve and modernize the iOS application. My contributions included improving architectural structure, optimizing performance, and supporting feature development to ensure a seamless experience for end users. Across these projects, I served as the main iOS developer, taking ownership of technical decisions including selecting the tech stack and defining the application architecture. I led the implementation of core product features, ensuring scalability, maintainability, and performance from the ground up. I implemented offline data persistence using Core Data, designed modular architecture solutions, and worked closely with backend engineers and product designers to deliver stable, high-performance releases aligned with business goals. Beyond mobile development, I’m deeply focused on frontier technologies — particularly Web3 and AI. Core strengths: • Swift, SwiftUI, UIKit • RxSwift, Combine, async/await • REST APIs, Web3 integrations • Core Data, Keychain • Modular architecture & refactoring • Performance optimization & release stability I also run a Telegram channel where I share practical iOS code snippets, AI breakthroughs, and tech trends that actually matter — with a pinch of philosophy thrown in.
