Managing Director at PatentMaker Software GmbH

We have been very lucky to have found Mehul and his team for our projects including the relaunch of our website, the redesign of our presentation. Mehul and his team are communicative. Mehul speaks very good English and coordinates every step in the projects. Not only does he implement our wishes and ideas, but also he brings in his ideas and suggestions that make the whole result very satisfying. We are very happy with the result Mehul and his team delivered.

Eivind Semb
Founder & CEO at Coinpanda

I decided to hire Mehul after carefully screening several developers for my project of building a web application. He was very cooperating during screening process and gave me the trust that he would be capable of delivering the project according to all requirements. The project turned out to be much more complicated than expected, and Mehul solved all technical challenges that we faced (both backend and frontend). His philosophy that "everything is possible" gave me the trust that the final application would be 100% according to my expectations. Communication has also been very good and effective during the project. I would highly recommend Mehul for any web application project, and I will likely hire him in the future as well.

I'm thrilled to recommend Rainstream Technologies for projects of any size. They not only delivered a final product that surpassed my expectations, but they were also incredibly supportive throughout the entire process. Whenever I encountered an issue, they were readily available to assist and ensure everything was resolved promptly. I already have another active project with them.. This is for sure long partnership! Rainstream Technologies has been my goto company for any development work. They always deliver quality work!

Laurens V
Owner of Touring app

Rainstream Technologies was able to solve some issues that couldn't be solved by other developers. They made the difference by really diving into the issue and finding their own way into solving it. We gladly continued working with them until we came to a first version witch which we're really happy. We have new projects on our future timeline and are really looking forward to work with them again. Our platform had some issues and we went through 2 developers already trying to fix it. Rainstream Technologies was the first to actually investigate and thoroughly understand the issues in order to fix them. I continued working with them for further development and have not regretted this for one second. Will continue to work with him in the future.

I have had the most incredible experience with Rainstream. From my first communication they got what I needed. The team have been extraordinary in their knowledge, skill, fixes, with my feedback, going way beyond what was expected supporting me well after the final payment with the logistics of developing an app to get to trial phase. I can not recommend highly enough. English perfect. My tech/IT knowledge is very limited. I can't even believe I have been able to achieve what I have so o far with Rainstream. So patient and generous with me from day 1. Incredible.
