      eCommerce Development Review from André Schörnig

      We have been working with Dinarys on our Shopify store for quite some time, and the experience has been great. From the very beginning, communication was clear, efficient, and reliable. The Dinarys team consistently delivered detailed proposals, stuck to agreed timelines, and offered well-structured solutions tailored to our needs. Their technical expertise is impressive, but what really sets them apart is their proactive attitude and genuine commitment to our project. Whenever we had questions or changes, they responded quickly and constructively. Its a true pleasure to work with a partner who feels like an extension of our own team. Highly recommended!

      Web Development Review from Nissrine Kohen

      Weve been working with Dinarys for quite some time now, mainly collaborating on Magento and Shopware development projects. Their developers consistently show solid technical expertise and a good understanding of our expectations and workflow. Communication is generally smooth, and response times are quick. Whenever issues arise, the team is open to feedback and acts quickly to improve. Over time, weve seen a positive evolution in their proactiveness and alignment with our teams way of working. They are flexible and collaborative, and its clear that they genuinely aim to build long-term partnerships. For the quality delivered, we feel the pricing is fair and transparent. All in all, weve been satisfied with our cooperation and would recommend Dinarys as a development partner, especially for companies looking for experienced backend developers in Magento and Shopware.

      Web App Review from Michael Paskow

      Dogtown media helped to develop a new cross-platform app and web portal for a sleep health study involving insomniacs for the National Sleep Foundation. The team was reliable and developed an excellent experience for end-users. It has been a great experience working with DTM. The team is reliable and communicative. They come up with creative solutions and are always available for any and all maintenance issues that arise. Although I am not well-versed in pricing for app development, I do feel that the pricing may have been a little too steep. That said, the work they have produced is excellent, and I'm very happy I got to work with the team at DTM.

      We've really enjoyed the time spent with Dogtown and their support in our product initiatives. They have always been readily available to talk through design ideas, technical challenges, or feature improvements. Communication has always been solid, with a reliable stream of beta builds (delivered to our own devices to test out) and detailed patch notes. We look forward to working with Dogtown on more projects in the future!

      From my initial consultation to the completion of the development process, the entire team at AppStem has been a pleasure to work with. With so many Mobile App Development companies to choose from, it's important to chose one who is willing to understand your needs and clearly outline a game plan before getting into development. If you're looking for more of a partner than just an agency, you're in good hands with AppStem.
