I've been working at j‑labs for almost six years , and I have the opportunity to observe the company's development. Despite the truly dynamic growth, the company manages to avoid a dry, corporate atmosphere and bureaucracy, which is a significant advantage. The ability to switch projects within the company is another major plus.

For me, j‑labs is, above all, committed people with whom I can implement bold projects, both business and personal. In addition to working for one of the largest technology companies in the world, I take part and engage in organizing events promoting new technologies, programming and the development of digital competences. Conferences, workshops, meetings with interesting speakers - all this allows me to develop comprehensively (not only technically!) and share my experience with others. And at the same time meet a lot of cool people!

I still remember the first call from the j‑labs recruitment department. The series of uninteresting employment processes for other companies was interrupted with a huge dose of professionalism. In addition to continuous development for the client, both professional and financial, on behalf of j‑labs I met dozens of people during technical evaluations, created games, conducted training, made public appearances, and currently am leading a project to revolutionize the recruitment process.

For me, working at j‑labs is a fascinating journey into the world of technology and personal development. Right from the recruitment and technical interview itself, I felt the amazing atmosphere in the company. j‑labs encourages engineers to constantly improve and find their own development path. I got the opportunity to work in an international environment and meet people from all over the world, and this is what gives me incredible joy and satisfaction. I also conduct recruitment interviews and actively participate in the j‑Tech League project - an innovative approach to technical recruitment. After many years of cooperation, I joined j‑labs directly as a Delivery Manager.

j-labs is the human side of IT, really good IT. Thanks to j‑labs and the client, I was able to learn Blockchain from scratch, and today, after 4 years, I am giving lectures, sharing the acquired knowledge and experience. My work is appreciated and respected, which gives me a sense of professional fulfillment, and integration and sports challenges create a great atmosphere. Become one of us - j-People are, above all, people, not just lines of code!
