      Fintech Review from Sergei Lishchenko

      The exception team the client collaborated with brought in fresh ideas and innovative technologies previously unfamiliar to the client. For example, with Yalantis' guidance, the client's developers explore the Go language. The primary reason the client chose Yalantis is its strong organizational and project management skills. It's not just about the developers; Yalantis provides a comprehensive support framework, ensuring that a project manager is consistently present. (Verified via email)

      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.

    • Greg Lipper
      Greg Lipper Managing Director at Happi Pte Ltd
      5.0

      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.
