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.
Head of Sales
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. ;)
Back-End Developer
Paweł's 16 years of experience in programming various applications makes him one of the most experienced programmers in our company. He created the first website in the 6th grade of elementary school and as you can see, the passion for programming has been with him forever. After work, he likes to go fishing and watch a good series. He also has a very talented daughter who sings very beautifully.
Marcin has been working for GMI practically since the beginning of the company's history. He is one of those developers who can come up with completely unconventional solutions for every problem he encounters. Moreover, he is a passionate player. Thousands of thousands spent in CSGO and hundreds in PUBG proves how much he likes to spend his free time outside of work.

With the greatest pleasure and full responsibility, we recommend GMI as a professional contractor for web applications and CMS systems. We chose GMI primarily because they approached our inquiry very professionally. Very fluent contact at an early stage of talks announced that the implementation would be equally efficient and it actually was.

If there is an opportunity in the future to jointly implement another project, we will definitely use the services of GMI again.
