About

In mobile since 2013, mostly on Apple platforms.

I'm a software engineer in Warsaw. I started in 2013 with iOS and Windows Mobile, became a senior iOS developer at Wimix, and now lead the Flutter team at Solbeg. After hours I design, build and ship my own apps.

iOS developer, middle to senior · Wimix

I joined as a middle iOS developer and left as a senior. In five years I completed many apps for clients in different parts of the world, among them a sports platform that connects athletes, coaches and clubs, with live streaming, real-time statistics and social features. I designed and built new features, kept the code to industry standards, and set up shared development practices with the team. It is also where I started with Flutter.

What I take on

Only things I have already done, for clients or in my own apps.

  • Leading a Flutter team I lead the Flutter team at Solbeg and choose the stack for new projects. Five Flutter apps delivered for clients.
  • Native iOS SwiftUI and UIKit, Combine and Swift Concurrency. Over 15 native iOS apps delivered for clients since 2013.
  • macOS tools JaySnake, a native JSON viewer, editor and code generator, is on the Mac App Store. GitCrab, a Git client written in Swift, is in development.
  • Offline-first, on-device apps All of my own apps work offline, with no servers and no accounts. Inkweave generates every crossword grid on the device.
  • Real-time and payments Chat, live updates and sync over WebSocket, Socket.IO and gRPC. Payments and subscriptions with Stripe, Apple Pay and StoreKit.
  • An app through App Store release, solo Five of my own apps are on the App Store. I designed, built, tested and submitted each of them myself.

Now — September 2026

At work I lead the Flutter team at Solbeg. We build Windows and mobile versions of client apps on Flutter and native iOS.

After hours I'm building three apps: Crystal Depths, a match-3 for iPhone; GitCrab, a native macOS Git client written in Swift; and Peek-a-Maze, an offline maze puzzle for iPhone and iPad.

Off the clock: board games.
