Cooperation with DEV PACK has been a very pleasant experience for us as a client from the very beginning. Until then, we always struggled with unfinished work, unfinished functionalities, and in order to explain individual errors to programmers, we had to devote a lot of time to our own research into what doesn’t work for us, where things are written, etc. We really don’t have the time or skills to do that. The moment we took over the complete retesting, coordination with the supplier and proper description of errors in the DEV PACK, we didn’t have to worry about anything. I appreciate the professional performance, above-standard client approach, adherence to the agreed deadlines. I warmly recommend.
