Our customers about us
We like to listen about our cooperation
„I have been cooperating with DJ-Extenions for several years. I commissioned the implementation of several projects and during each of them the company showed high professionalism, knowledge, experience and, above all, understanding the client's needs. Each order was completed on time and, most importantly, within the assumed budget.“
Kastell - Patryk Jaworski
„The online store is another task entrusted to DJ-Extensions, which was exemplary, and the store component itself fully meets the expectations. And the best thing is that for a performer, nothing is practically impossible. We appreciate. Working in a similar industry, I know well that seemingly simple functions can turn out to be labor-intensive. We can always count on DJ-Extensions.“
YetiForce Sp. z o.o. - Błażej Pabiszczak
„We were looking for a company that would devote so much time to us to create a user-friendly and administrator-friendly website. The DJ-Extensions team not only reacted to changes in the design in real time, but also had the courage to suggest their own solutions, thanks to which the final product revolutionized Balex Metal's communication rules.“
Balex Metal - Konrad Spuła
