GCD tutor
I am a mobile and web developer, technical mentor, and consultant with over 15 years of experience. While I currently specialize in mobile development, both native and cross-platform, my background includes significant work on frontend and backend systems, giving me a comprehensive understanding of the entire development lifecycle. If you are interested in discussing architecture for your mobile app — from backend services to client-side implementation — or if you need a mentor or code reviewer, please feel free to connect with me on LinkedIn or Twitter.

I've been an experienced programming contestant and for that reason my style of solving problems became like fast and correct - that's everything we need. Writing code has been my hobby since I was 13 and it's the perfect age for studying IT. Those circumstances gave me an ability not only to repeat after another programmers, but also to develop my own tricks, ways of solving problems.

I work on the Swift compiler for fun. If you use Swift, you're running my code! I run an iOS development company. My clients include Fortune 500s, governments, and startups. I'm a hacker at heart and I like solving difficult technical challenges. I know my way around graph theory, compiler/interpreter internals, algorithm design, computer vision, project management, test design, and much more. Chances are, if you have a problem that can be solved by writing software, I can help.

Hey! 👋 I'm Andrii - I've been making iPhone apps for 8 years and I'd love to help you learn iOS development! What you'll get when learning with me: * I'll help you land your dream job by polishing your resume and practicing interview questions. Having worked on many different apps, I'll share what actually works in the real world. * You'll learn everything you need - SwiftUI, UIKit, working with data, networking - but we'll take it step by step so you really understand it. I'll show you how to write clean code that's easy to maintain and how to use Xcode like a pro. * Everyone learns differently, so we'll find what works best for you. We'll work on real projects together so you can practice and build up your portfolio. I'll be there to help whenever you get stuck. * I've helped many junior devs grow into confident iOS developers. We'll combine coding exercises with real project work to help you progress from basics to advanced stuff. Want to chat about your goals or get help with code? Book a session with me and let's start building your iOS dev career! Message me to get started! 🚀
GCD tutor
I help teams fix expensive iOS problems in products that already exist. My work is strongest where mobile execution has become a bottleneck: slow SwiftUI screens, architecture drag, fragile releases, App Store blockers, modernization pressure, hardware/device integrations, or rewrites that are starting to look too risky. Most recently, I architected and built a regulated medical device iOS app from concept through multiple production releases, owning core architecture across state management, data flow, device interaction, reliability, and cross-functional delivery with hardware, firmware, backend, and product teams. I’m hands-on in Swift and SwiftUI, but I also bring technical leadership through architecture direction, code review, mentoring, planning, and helping teams make changes without losing delivery momentum.

Samir Habib Zahmani
GCD tutor
“I'm very grateful for all the support that I've received from Shawn sofar. I wanted to learn more about the basics of engineering so that I could use coding agents such as Claude Code and Cursor more confidently, and Shawn has acted as a true mentor in this regard. Always patient, solution oriented and taking the time to explain (and repeat) things, I'm really enjoying learning from Shawn.“
