Steven Eichele CEO, 210 Tech LLC
USA USA

We were looking for a company to develop an iOS & Android app. Our goal was to find the right company to build a relationship with, Artjoker exceeded our expectations.

100% professional and organized. From day 1, we have had weekly meetings, and two week scrums. We have used email and video calls to communicate, and google sheets to share project info. Every step has been documented by the project manager.

Their development knowledge and experience has been really great. I can't say enough about their professionalism, communication, and organization skills.

Communication was prompt, and the management and other team members responded quickly and directly to the point, helping us identify and estimate our needs.

When we encountered difficult technical or business moments during development, they quickly connected us with other specialists in the company, including top-level management such as the CEO and CTO, to help us as much as possible within a short time and free of charge. Although there were only a few such cases during different project phases, it worked amazingly!

Management has been quick to respond and prioritize. If something critical happened, then the team immediately began working on a solution. We always knew that if a task had been given, then a task would be completed. Project manager was always accessible and quick to respond.

The breadth and width of skill within the company were impressive. Whether I needed a programmer, a designer, a business analyst, or other, Artjoker always had the needed skill in-house, and always delivered the highest quality.

They’re very skilled in the technologies they use and excellent with UX.
