our team


Android Developer

With over 9 years of experience in creating Android apps, Grzegorz is the person-to-go when you need a help with a project. He also develops apps with Flutter and after hours, he even dabbles in game development.


iOS Developer

Apple fanboy with 10 years of iOS developer experience. Bartek loves challenges and, currently, SwiftUI. New technology and clean code are his fuel. On the weekends, you can meet him home brewing, juggling, or traveling.


QA Specialist

Karolina makes sure our apps perform flawlessly. She tracks down the errors and monitors the quality of the products. In her spare time, Karolina likes to sit with a good book – she’s a real speed-reading master.

Carefully selected projects

With each product we create, we want to solve users’ problems and support the client’s business. We also want to learn something new. That’s the reason why we avoid projects with technical debt and work with clients from many different industries. This way we can get to know innovative solutions. Such an approach lets us build apps that get wider recognition. Two of our apps have been nominated to Mobile Trends Awards, and one app received a Legal Bookmakers Award.

Experienced team

Our software developers have 4 to 10 years of experience in building apps. Together we’ve created over 60 projects for Polish and foreign clients. With us, you’ll be surrounded by experts who know the industry inside out and are always willing to help. You have a challenging task you can’t figure out on your own? Just ask us a question – we’re here to support you.

Growth-oriented culture

Building products for our clients isn’t the only way we develop our skills. We also organize meetings and watch conferences or IT-related movies together. If you want, you can also start a course or take part in our internal project. You have your own idea for an event or training? It doesn’t have to be directly related to what you do on a daily basis. If you think, it can make your work better, we’d like to hear more about it.
