Altoros Labs Reviews & Testimonials
Daria Stolyar
Manager at Custom Software Development Company
5.0★
Software Development Review from Daria Stolyar
We hired Altoros engineers as an essential extension of our client-facing internal teams. This was a tough decision because our reputation as a brand depends on the overall efficiency of our processes and we needed to make sure all risks are mitigated when it comes to delivery. Altoros has not let us down.
Together with Altorosians we successfully deployed a number of tough and technologically complex projects on time. So our collaboration is certainly set to continue.

Ruby on Rails Review from Greg Lipper
In my 30 years in the software business, I have never had as positive an experience with an outsourced development services provider as I have with Altoros. Each Altoros engineer we have worked with has been strong technically, estimated development times accurately, completed projects on time, and delivered code and projects with high quality. Beyond that, they have helped improve our thinking and approach with suggestions and ideas that were better than the spec of instructions we supplied.

Software Development Review from Daniel Rondell
We are notably satisfied with the upshot. PMs and development team was very devoted to the tasks and encouraging. We had a stringent and fixed deadline. And we got it just in time! KitRUM helped us to create an entire software that absolutely meets our requirement. They had presented the system in a short-term after putting their hands on it. They also provide support after developing this software. We have a different project now and certainly will work with KitRUM again.

Software Development Review from Adelina Romanova
KitRUM expanded our team to shift software to a new platform. Using JavaScript and RESTful APIs, they improved interfaces and DevOps, and fixed bugs. The team has always been on time. Their ability to understand the business requirements and their communication was just perfect. I definitely will recommend KitRUM as a reliable partner.
Daisy Skot
Client Manager at Nicholas Financial Inc.

Software Development Review from Daisy Skot
KitRUM made a variety of development services: conception, coding, and QA, which means almost a full software package for our company. We needed to develop a few tasks, for example, a desktop app for our store, a cloud app for administration and supervision, and a portable app for end customers. However, we had an in-house team, which is not enough for this project. So we had to find a dedicated team that could deliver all we needed. We found KitRUM as a top-notch software development company

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.

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.

Olena Vandio's Review Sourced from Google
The company is constantly improving along wiht all the employees. I especially liked that communication is open and honest. Help will always be provided or redirected to relevant people who can best explain the details.
Incora has clear processes in day-to-day work, so no endless approvals to talk to C-executives. Among benefits also positive attitude to initiatives and detailed feedback.
My sincere recommendation!
