Web Development Review from Alexander Nikolaevsky
We have hired the Plavno team to develop a cryptocurrency exchange solution.allow users to make cryptocurrency transactions legally and transparently. Plavno team had to create a solution independent of third-party developers, develop frontend solutions for clients and service administrators, build a full-featured back-end that would include integration with banking and payment systems, and a multifunction module for managing currency exchange transactions, exchange rates.
Mitya Smusin CEO at Yellow Systems

Financial Review from Mitya Smusin
Some problems can only be solved with code, but others require end-user thinking. So Plavno developers remember that the whole goal is to solve problems — not only to write code. They thought about the problem from the restaurantants point of view.They developed a food delivery app with both customer and admim panels, which covers all the necessary functionality.
Yana Romanovskaya Product Manager at Beeline

IT Outsourcing Review from Yana Romanovskaya
Plavno was creating profiles with pulling up a lot of information (clusters). Xunit-based scoring was used when setting up a .NET 2.0 project. Scoring for this format works similarly to Junit. The team extended the products by adding features, fixing bugs. This development can change cluster parameters, cluster management system (current state of the object), customize vectors that lead to this cluster and make predictions.

Educational Review from Dmitriy Ksendzovsky
I have had an positive experience working with Exaud on expanding and maintaining several software products. Our software consulting technology stack is quite wide, from embedded development to mobile game dev, making it challenging to find the right partner knowledgeable in a number of these areas. The Exaud team is professional, flexible and continues to provide the development expertise we require to fulfill our project needs on time and budget.

Enterprise Review from Tim Martin
We have a very long history of working with Exuad, which in itself is about the best endorsement you can have. We have been working with them on projects for going on 10 years and they are our go to external dev team. Georg and team are not only very talented they are highly ethical. To me the later point is the most important, you can trust that they will provide high quality work and you can absolutely trust them on the business side.

SumatoSoft Reviews & Testimonials
Sergey Novik Co-Founder at El Pixel
5.0★
Staff Augmentation Review from Sergey Novik
Were developing an internal image processing tool for our design team and needed two machine learning engineers, since our core developers were busy with other client projects. We required extra hands familiar with Python and computer vision, so after a developers market review, we hired them from SumatoSoft.The SumatoSoft developers joined our team and were able to swiftly adapt to our workflows, which resulted in them delivering the working models well before our hard deadline.Communication was straightforward throughout the engagement. We had video calls and exchanged brief text updates on a weekly basis. The delivered code is clean, and pull requests are well-documented.I appreciate that they pushed back on a few of our initial architecture ideas. They challenged our original approach and proposed a better method for handling the model weights. We plan to bring them back for the next phase of development.
Domien Van Eynde Team Lead at Daiokan

Web Development Review from Domien Van Eynde
SumatoSoft is the firm to work with if you want to keep up to high standards. The professional workflows they stick to result in exceptional quality. Important, they help you think with the business logic of your application and they don’t blindly follow what you are saying. Which is super important. Overall, great skills, good communication, and happy with the results so far.

eCommerce Development Review from Alexander McCaig

AMYGDAL has been helping us with mobile app design and development for iOS and Android. They've helped us create everything from the ground up and have been with us every step of the way, from the ignition to now.AMYGDAL has helped us find ways to save time and money when it pertains to certain functionalities and offerings. They're very tight on timing and keep themselves to a high standard. They're very polite and understanding. Its been very eye-opening and refreshing to work with them. AMYGDAL is incredibly thoughtful and dedicated to whatever project they work on. They're not rigid at all; they're very comfortable to talk to and work with.For the time we've known AMYGDAL, they've never shown any place where they need to improve.
