Kolosek is an open source software company. This means that those services we don’t offer within the company, we develop and share openly.
Why do we invest so much time in open source programming?
Because it benefits the community, as well as our team. On the one hand, we get to practice our skills and develop something we need, and on the other, we have a chance to contribute to the community. Also, we use open source projects and in most cases, we try to improve their current versions and give back to both contributors and the community.
