Aristek Systems Reviews & Testimonials

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.

Web Design Review from Undisclosed
Aristek Systems has redesigned the UI/UX of an existing educational digital platform. The team has refreshed the interface and added new features to deliver a more comprehensive experience for users. The client is satisfied with Aristek Systems' work and performance. The team delivers within the specified timeframe and manages the project seamlessly. Moreover, they stand out for their availability, problem-solving capabilities, and amazing work culture; they're easy to work with.

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.

SunTec India Reviews & Testimonials

Shopify Review from Joe Di Lucci
The ideal solution provider for every eCommerce store setup and optimization issues. We wanted our new Shopify store to get great brand visibility and conversions but lacked the resources and expertise for it. Partnering with SunTec India gave us access to experts who competently assessed our problems, solving them with creative product descriptions, SEO strategy generation, and product data entry service, bringing us on par with our competition.

Amazon Review from Walter Venkel
Excellent Amazon eStore product listing and advertising support that skyrocketed our sales.Our corporate gifting eCommerce startup faced the problem of poor brand visibility on Amazon. We partnered with SunTec India to handle the problem and were delighted with the results. They sorted our products and listed them accordingly while optimizing our PPC campaign to give better ROI. They're now our permanent partner for the job.

Web Development Review from Randy Linker
The web development partner that can give bespoke websites within a tight schedule and budget.Our company deals with supplying industrial equipment procured from many manufacturers to clients of various industries. We had not been doing this well due to the lack of traffic-generating capabilities of our incumbent website. SunTec India fixed its content and SEO issues, making it more appealing to our target group. We've now become standout suppliers in our industry; thanks to SunTec India.

Can't say enough about this group! Amazing work and great people. You can really tell that the culture here is far above other shops because everyone seemingly loves what they do, and it shows in the final product. Solid work, agreeable rates, and on time delivery. 100% recommend!
Ernesto Berrum's Review Sourced from Google
Great group of people to work with. Very flexible and have been delivering on all of our request in a timely manner. Our platform runs on Ruby on Rails but they have Python, Node.js, React, React, and HTML experts on hand.
