Clients love us

It’s been a real pleasure to work with Vadim, Sergey and Alexander. They have been professional throughout, and know what they are doing. Many thanks to them and all the team at Sibers.

Many thanks and also wishing the Sibers team a wonderful holiday season, looking forward to our work together next year.

Awesome work guys and girls, super impressed. You have no idea how many people are desperate to use this tool!

Well, I am satisfied with their performance. If Edil has any questions, he usually contacts me and our frontend developer Shon. He suggest some solutions for particular issues and he can even work late hours when it’s needed. So I appreciate his input very much. Vadim is also taking part in our discussions, but I don’t work with him so much. Overall, I enjoy working with them and I don’t have any complaints.

Sibers are very easy to work with! Highly recommended!

We are extremely impressed with team, the changes are absolutely fantastic and will make a huge difference to our business when this product is completed!

I have been using upwork a long time. This team is my favorite. I do all my projects only with them now. They developed my web based app and smart phone app very quickly and from best quality. What I appreciate the most is that they don t reinvent the wheel, and guide me to find solution the most cost effective but impactful. I highly recommend this team.

Sibers have been a great long term development team.

I hired Sibers for a full stack iOS App and Website Development. This was my first ever development, freelance job, new app, and business venture and using Sibers made the process extremely easy. I interviewed a few freelancers prior to hiring. Sibers was the most knowledgeable from a technical and business standpoint; they made recommendations and provided guidance to my rough draft/ideas. They stood out from the rest who rather make a sale instead of trying to understand the business. After hiring, they sent me tons of questions about the flow of the app to ensure that everyone was on the same page from a development standpoint prior to getting started. The Sibers team was extremely responsive and quick to develop. For 3 months, we messaged on a daily basis which was excellent. Besides the time change, contacting them was never an issue. Every day that went by, I received a status update on the work that was done. They never did anything without giving me updates on the project. If I wanted to make changes, they provided feedback and possible other options that might be better. They asked for approvals with any changes. The team was able to integrate into 3rd party site/apps, such as AWS, Sendgrid, and Twilio. They hosted a server for me during development and then setup and moved everything over to AWS (my choice, they gave options). I have zero technical background, so this was extremely important. Within 3 months, I had a brand new website and iOS app. There were absolutely no hiccups getting my app into the app store, which is not easy to do. They met all the guidelines of Apple and i'm extremely happy. I'm able to manage the app from the admin portal they created for me and it's working perfectly. Sibers was extremely professional, had multiple departments that took care of me from billings to account management. I couldn't speak more highly about the team and my main daily contact, Eugenia, who was there every step of the way. Thank you for a full turnkey solution!
