About me
Swiftoletz Brothers
We’re four friends from Wrocław. We met while working at the software house almost a decade ago, and together we’ve already delivered more than a dozen projects.
What do we do?
We build products from start to finish: from planning and design through development and testing to deployment and maintenance.
[* software systems
- mobile apps for iOS and Android

One team, the entire product.
After hours, we develop our own project — Peakme, available on the App Store. We can also deliver an MVP or provide extra development capacity when your software house needs it.
Technologies
JavaScript, TypeScript, React, Angular, Swift, SwiftUI, Kotlin, Java, C# and Go. We also handle backend development, CI/CD and app store releases.
