Polish IT Community Report 2022

What type of programmer are you?

The highest number of developers, 41%, work in the backend layer. A year ago, it was similarly 40%. The last few years also show a clear trend toward fullstack specialization. We are observing more and more job offers for this position. However, this profession requires experience. Despite the need in the market, the percentage of these specialists is not growing rapidly. Last year's report results show a similar ratio of Fullstack Developers compared to the rest of developers. Frontend remains unchanged, slight increase of Mobile Developers.
