Dominique Dujardin VP IT Shared Services Europe chez XPO Logistics Europe at XPO Logistics Europe
5.0★
Software Development Review from Dominique Dujardin
The product was developed successfully and has been undergoing pilot usage. Hexagon IT Solutions managed the engagement effectively, delegating tasks and assignments between us and the team. They met timelines and communicated efficiently through Slack. Their resources also resolved bugs quickly.Hexagon makes it easy for people trying to develop software. Ultimately, Hexagon was and has been on the same page with us from the beginning. They knew exactly what we were looking for, and what we didn't want. Other software development firms jumped at us with marketing proposals, designers, and irrelevant business consulting. Hexagon IT Solutions took the time to understand who we are and offer us their services accordingly.
Edona Haliti FOUNDER at Electric Mobility LLC

Their efficiency and timely delivery have been hallmarks of their work.Communication and Response time, and the execution. They have provided us with quality of work within the stipulated time. Their affordable rates are a cherry on the cake. It's difficult to find these kinds of perfect combinations.

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.

Caring Gene's Review Sourced from Google
Troy Web took over the maintenance and service contract for our in depth healthcare career information and job posting website. Their ability to seamlessly take ownership, clean up and bring our site into a stable wordpress environment was done not only quickly, but also flawlessly. During our time with Troy Web, a number of updates and additional features were required to be built. They were not only able to build these aspects, but also to correct past build issues in the process making the site more reliable on a daily basis. In the last 6 months of their service we didn’t experience any unforeseen downtime with our website, which is extremely important to the function of our site for those that access and use it on a daily basis. Troy Web provides an exceptional service with a team that is always available and very knowledgeable.

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.

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.
5.0★
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

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.

May Halpirn's Review Sourced from Google
Curious about another reviewer who looked older, a job applicant, who didn't have his call returned. Frogslayer slung cliche pablum his way. Apparently they hire Jr. Devs but do they hire over a certain age? Do they know the law? Their Senior Dev is under 30 and was hired from being a student employee. Curious and curiouser. Maybe Frogslayer isn't as woke as they appear. Friend of mine went through the ringer with them was told they'd get feedback either way. Instead they got the standard blow off rejection after devoting way too much time on a company that might not value "employees over a certain age." Heads up Frogslayer. There are laws.
