We work with

React Native is a framework for building mobile applications using JavaScript and React. It allows developers to create cross-platform apps that can run on iOS and Android and many more! It uses a single codebase, making development more efficient and cost-effective.
React is a powerful JavaScript library for building user interfaces, renowned for its efficiency and flexibility. It enables developers to create dynamic and responsive web applications with reusable components, streamlining the development process. By emphasizing a virtual DOM, React ensures optimal performance and a seamless user experience across diverse web platforms.
JavaScript is a versatile and widely used programming language that runs in web browsers, making it essential for building interactive and dynamic web applications. It is also commonly used for server-side development with Node.js.
TypeScript is a superset of JavaScript that adds static typing to the language. It provides developers with tools for catching type-related errors during development, improving code quality, and making it easier to maintain large codebases.

Our clients words

Christian Schultheiss
Technical Coordinator @Talentbay
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.
Bartłomiej Tyranowski
CTO @Picodi
We needed a solid partner to help us launch a new mobile app and make Picodi available in the mobile ecosystem. Had a functional scope defined, the API and the assets mostly ready, but did not have much experience in mobile development. Also, didn’t have much time. That’s why we decided to partner with TWG to help us make that project a reality. Faced with a stringent deadline, The Widlarz Group delivered a mobile app that became a solid MVP of Picodi Cashback on mobile devices. Also technically the app kept very high standards and the CI/CD pipeline that was established during the development period made it quite easy to maintain at later stages as well. TWG was a very good support for our internal engineering team in a time when we needed a solid software quality and a very fast pace of development. I can definitely recommend TWG, especially for such cases
Piotr Szacinski
Co-Founder & CTO @SmartCourt
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.
Katarzyna
Marketing manager @ Ice cream company
We came down to earth with our expectations and understood what we can and cannot do. Certainly the workshop systematized our visions and ideas, and highlighted the doubts we should have before jumping into the project.
[Undisclosed]
CTO @ Closer
The team we were working with immediately understood our challenges. Their developers delved deep into our React-based app, employing TypeScript for precise static typing. They managed the global state, ensuring the app's reliability with detailed testing, and were thorough in fixing bugs and fine-tuning ahead of the release. Their ability to translate our Figma mockups into functional screens was impressive. Moreover, their implementation of the complex multi-step form and constant communication with our developers ensured our objectives were met.
Adam Moreau
Co-Founder at FlexPro Grip
Working with TWG has enabled us to accelerate FlexPro Grip's trajectory tremendously. The uniquely skilled individuals bring insights to development resulting in a think tank-style of collaboration. TWG strives to be better every step of the way. They want honest feedback constantly. And moreover, this feedback will be applied. They are always pushing forward and working to improve.
Gavin Keipp-Stroud
Director of Operations at FlexPro Grip
The Widlarz group has been exceptional to work with. They have been great partners and have greatly enhanced the quality and reliability of our mobile application in the time we have worked with them.
Omar Diop
Technical Lead at Learnn
Working with TWG has been a game-changer for our app. Their expertise in React Native and the react-native-video library was crucial to overcoming our challenges. The audit provided a clear, actionable plan, and their implementation was smooth and professional. We're thrilled with the results and look forward to continuing our collaboration.
Daryl Moreau
CEO/Founder at FlexPro Grip
Before working with TWG, we were a bit concerned that working with a non-US developer might be a problem due to either a language barrier or differences in time zones, but neither of these have ever been a problem. After experiencing disappointments with 2 prior app developers, we feel fortunate to have found TWG. In addition to the expertise provided by its developers, the TWG team consistently delivers value by paying strong attention to detail, transparency, and effective communication.
