«Dad threw his cigarette to the ground, crushed it with his boot, blew out the last bit of smoke, and, without taking his eyes off the wall, said, 'Now, dont yall ever tell me theres something you cant do.' Then he walked back into his shop and resumed working.» «Will» book by Will Smith.

Do you want to grow? Do you want to develop yourself as a professional? Do you want to evolve as an individual? Are you eager to achieve results? Are you ready to work hard on yourself? If your answer to all these questions is a confident YES, then our company is the right place for you.

The company has developed a program called Company Bootcamp, which allows you to gain the necessary knowledge and practical skills required for each project. Youll not only study but also apply organizational and technical regulations in practice. Whether you have 7 or 15 years of experience, you will still learn something new during the onboarding stage. If you are a Starter or Junior, this program will become an intensive training for you. Company Bootcamp lasts 1 month for all positions and 2 months for backend developers and is fully paid.

«Eat a little quicker, hit the brakes on your commute a little less, and sleep a little faster and youll have found the hours you need. So dont tell me you dont have time to train, or to study, or to write, or to network, or to do whatever you need to do to achieve your vision.» «Be Useful: Seven Tools for Life» book by Arnold Schwarzenegger.

After successfully completing the onboarding and starting your collaboration with us, you will receive a PDP (Personal Development Plan). Your PM will help you plan your further growth and learning during your free time. Additionally, you will gain expertise in a variety of technologies depending on the projects you are assigned to. We also offer English courses twice a week.

Within the PDP framework, you can deepen your knowledge in your current field or even switch to a different direction. At our company, you will continue to grow constantly, with small breaks as per our guidelines, allowing you to enjoy the moment and then proceed with your development.
