      Software Development Review from Harshal Chhajed

      They have highly skilled support staff for faster resolution which leads to customer satisfaction. Also, it has many features including IoT and blockchain apart from regular software development. If there are any changes in the scope of the project at a later stage, it can prove quite costly and also difficult to accommodate last-minute client-side scripting changes. They are versatile, cost-effective, and offer quick customer support. They offer a very customized software development tool where business needs can be addressed. It is very cost-optimized and hence can help generate good returns for business investment.

      Web Development Review from Evan Merali

      We had a great experience working with Ezulix for the Web Development project. We were already impressed with their prolific experience in the same field coupled with reasonable pricing. Our project was complex and the architect at Ezulix conducted thorough review and displayed an impeccable understanding of the the functionalities and implementations. All of the deliveries were made in the timely manner. We highly recommend their services to anyone looking for blockchain application development.

      Ezulix has focus on a highly responsive portfolio management solution capable of handling thousands of large, complex projects. The agency developed core technologies for the platform while collaborating closely with their team. Although remote work posed some challenges, we remarked that Ezulix's efficient project manager worked diligently to solve communication issues.

      eCommerce Development Review from Ruth McMenamin

      The team rarely encounters a design that truly leaves them in awe, but Ezulix's work perfectly captured the desired temperament and even surpassed expectations. The feedback from existing users familiar with the old website has been overwhelmingly positive. Every aspect of the UX/UI design contributed to creating a website beyond what was initially envisioned. The team wholeheartedly recommends Ezulix for exceptional design solutions.

      Ben Lord's Review Sourced from Google

      I’m not usually one for making posts like this about other companies I do business with but given what I’ve experienced over the last 5 years, I feel very compelled to raising awareness into my experiences with Dotsquares. Initially, this company was very good at handling our website requirements. It was thanks to this that when I became the owner of Lorryspotting.com that I figured it would make sense to have them upgrade that website. It was a big project but with all the accolades and expertise that Dotsquares boasts about, it seemed to be within their scope of capability. Instead, it turned into the most miserable of projects that was riddled with the purest incompetence that I’ve had the misfortune to witness in almost 20 years of business. As per their terms of business, I advanced paid for part of the project yet they were incapable of delivering a functioning website. Added to this, the ageing status of the old site meant we suffered a server failure 16 months ago and when restoring the old site, it was proven that Dotsquares negligently compromised the colossal amount of data held on that site to potential hackers. By this point, enough was enough. Despite so-called “project managers” apparently understanding my business, they became mouthpieces with a catalogue of excuses and rhetoric that failed to take responsibility enveloped by expectations we would continue to pay to fix what they had caused. Ordinarily, escalating this to a company’s CEO should yield an immediate improvement to rectifying a situation. The CEO of this company ignored my email and relegated its handling to the very people causing the problem and failing to deliver any outcomes. It was therefore with no other alternative that I had to commence legal proceedings against this company. Despite repeated attempts to defend what was in essence an indefensible position, we reached a settlement on the matter, the terms of which I’m bound by a confidentiality order but has avoided it being played out before a Judge. Based on my reflections, this company may theoretically claim to value their customers but in reality their actions speak far louder. They do not deserve to be in business and I can’t even begin to fathom how they deal with some of the brands that their client list cites. I would absolutely urge anyone who does, or considers to work with them in any capacity to run for the hills - you will regret it otherwise! I only wish I had of checked out some of the reviews that are out there - reflecting on them now resonates virtually a carbon copy as to my experiences!

      Palak Vig's Review Sourced from Google

      I have been waiting for my website to be completed for two years now, and the experience has been increasingly frustrating. The lack of timely communication and follow-ups from their side has been disappointing. Despite my repeated efforts to get updates and move things forward, progress has been unreasonably slow. I expected a much higher level of professionalism and responsiveness. I hope they take this feedback seriously and improve their communication and delivery timelines moving forward.
