Web based applications

Your application is more than just lines of code arranged and connected in the right way. Understanding business goals and striving to provide end users with the best possible experiencet is the core of our thinking.

We specialize in technologies that will ensure error-free operation of every application. From a simple CMS to a complex ERP system.

We understand that the online product creation process is stressful. Thanks to the Agile methodology and the support of our Scrum Master, the implementation of the project always runs smoothly, and each of our clients receives support at every stage of the project.

Mobile applications

Your mobile application has stalled or never existed because you were scared of costs? We are able to take over any project or create it from scratch while paying attention to the budget.

By using hybrid and progressive technologies, we are able to provide you with two applications (Andorid, iOS) for the price of one! You will save time and money, and your business will be able to develop freely.

Our code, your brand - together we will create a fully scalable product that aims to conquer the mobile applications market.

Product Design Workshop

We create products, not just software, which means that during the entire implementation process we always focus on the value of the software for your company and end users.

If you have an idea for a business and you don't know how to take it all, our project team will help you at every stage by conducting workshops. The final effect is a complete information architecture, mock-ups and, if necessary, even a prototype of the application that you can present to, for example, investors.

We advise you not only how the application should look. We will tell you how to launch it on the market, how to plan marketing campaigns in such a way that the application will be successful at the lunch!

our core team - there are many more and we are constantly looking for new talents

The head of all bosses, the founder of GMI. Mikołaj is a specialist in fast product validation thanks to 10 years of experience implementing them from scratch. It focuses primarily on combining business and technology. A digital nomad who is also an avid cyclist.
Tech Leader
Back-end Developer for 12 years specializing in designing applications and IT systems from scratch. Leader of programmers and product design team. He is responsible for the quality of the code of each application and will not pass any error. In addition, he is a freak of role-playing games and a cat-stroking lover. :)
Scrum Master
Thanks to Peter, all projects are delivered on time and according to the schedule. The budget for him is sanctity, and the problems according to his definition don't exist. It's simply challenges! It connects the developer team and customers into one role. He is so busy man that when he has free time, he is most likely going to the basketball court with the ball. :) Outside of work, he organizes music festivals completely pro bono!
Front-End Developer
At some stage in his life, Daniel stated that he had to change something and became a programmer. From that moment on, it makes graphics designs a reality and does it very well! His enclave is a garage, where he loves to tinker.
Sales Director
An expert in building B2B and B2C relations. He perfectly captures the nature and mentality of our team. He is on the front line in our company and all projects pass through him. Programs at free time so that it is able to translate the programming language into "human" language. Passionate about everything that is related to the cosmos. He wants to build a house, and put a large telescope next to him to observe the universe.
Front-End Developer
Wojtek focuses primarily on discovering and implementing the latest solutions in application interfaces. Every mistake of the application is treated by him as a failure, so it checks several times before anything will show the customer. An enthusiastic snowboarder, bookstores cannot keep up with the printing of fantasy books for him.
Back-End Developer
Programmer for 10 years and created so many products that he is not able to count how many projects came from his keyboard. No industry is an obstacle for him. Perfectly finds itself in unusual solutions. Thanks to him, we know what real bread is! If he gets bored with programming, he'll probably set up a bakery. ;)
