Reviews

Ronald Demuth
President of Teal Ventures and Torrey Pines Investment
We turned to SDH after an unsatisfactory 8-months long experience with a different development team. The team at SDH helped us to redevelop an application for one of our start up projects in just 6 weeks. Thanks to SDH, we were able to preserve the growth trajectory of our project and move ahead with its roll out. These guys keep to their promised timeline and keep their word! We feel comfortable turning to SDH for help with our most complicated and time sensitive projects.

Lena Frenzel

It is imperative to have a reliable partner in the area of online services and application development. SDH has been that partner for our company since 2018. Working with the professionals at SDH is a pleasure as we can always be certain that our ideas will be heard and implemented as intended, and we can always rely on their very qualified advice.

Oleg Shmelev

The SDH team successfully developed a unique engine for our project that automatically scales depending on the required workload.
