What Our Clients Say?
We implemented the first version of our mobile application in React Native in cooperation with TheWidlarzGroup. A major asset was exceptional and efficient communication; feedback was applied immediately, and the development team was effective and involved from start to end. Especially the innovative team selection model, which ensured high-quality service at a reasonable (although not low) price, deserved notice. Our cooperation was very professional and if I had to do it all over again, I would choose TWG.
Piotr Szacinski
Co-Founder & CTO @SmartCourt
The team cares about the outcome of their work which is the final product. I would call it a product-centric software development and if I were to choose a team for my next project, I would choose The Widlarz Group. They are not just implementers, but also a reliable IT partner that I can trust. Software developers from the team know what they do, and they have created solutions with flexibility and extensibility in mind so that the code is future-proof. The service involved end-to-end software development, and the team has helped us with the design, quality, and mobile and web app development, all of the team members are smart and communicate well. Also, the team is well-organized, you can just sit down and see the product growing.

He's the one who brought this whole team into fruition. Before TWG he’s been working with humans and with machines and he loves doing both.

He's been a parkour athlete for 10years, now he's retired and enjoys other sports.
