      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!

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.

      Josh and the team at Matic Digital are skilled and creative technologists who delivered again and again throughout the project's lifecycle, adding value via their expertise, insights, and extensive experience. Whether you're looking for UX/UI design, experience, brand, and strategy consulting, or custom software development assistance, I can't recommend Matic Digital highly enough.

      niccolò calandri's Review Sourced from Google

      Unfortunately we didn't find ourselves in terms of development methodology and results. The work was not only late but was not even complete.When asked to do the bare minimum, they asked us for more money.After loud complaints, they restarted the development and completed the guaranteed minimum. Edited review.
