      Web Development Review from Undisclosed

      Aristek Systems developed, tested, and released a new website for an e-commerce development company. The team utilized Ruby on Rails, Elixir, Phoenix Framework, JavaScript, GraphQL, PostgreSQL, and AWS. Aristek Systems was able to deliver a fully functional software, much to the client's delight. The team was highly communicative, and internal stakeholders were particularly impressed with the vendor's professionalism and attention to detail.

      Software Development Review from Anonymous

      I had the privilege of working with Ruslan and his team at Aristek for the past three years. It is hard to find that level of dedication in an offshore vendor/partner but Ruslan and the Aristek team deliver it. I would highly recommend Ruslan and Aristek to anyone needing an expert level partner in EdTech and SaaS platform development.

      Amazing and talented people. I’ve worked for both client and agency side and can can say their partnership is amazing. They truly care about ongoing operations and not just ending it at a project level. Highly recommend! Message me if you want specifics.

      I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

      Been working with the guys at heroic for 20 years. These are top notch professionals with very deep experience. I have worked with them in the data center, on site and in the cloud. Have used them for managed services, large projects, small projects and everything in between. I trust them completely. Not only are they really great at what they do, they are also genuinely outstanding human beings. Look no further.
