We have been comparing the offers of 7 companies and selected DO OK, as the reviews of the projects they have completed were positive, and their vision of implementation of the project was close to our expectations. DO OK is willing to undertake any challenge we might encounter in the project and provide full support. Our web app was produced in short terms and fully relevant to the user story. The task was challenging, so the vendors we previously worked with either refused to attempt the project or could not deliver the product within the defined time limit.
