      Software Development Review from Rick Tomsic

      Global business segment growth is requiring technology to keep up with the increase. Our platform is designed to be scalable and able to be implemented across several nations. We collaborated with Closeloop Technologies to work with our staff in order to scale up the programme. An whole agile team is provided by Closeloop Technologies to participate in our programme. At first, we gave them the data in hopes that they would aid in our execution. They have combined Spring Boot, JavaScript, and AWS cloud technologies. The platform is a value stream and full-suite insurance lifecycle. It is an internal iterative software programme. Working with Closeloop Technologies is simple. They pick up new roles rapidly and possess agile team abilities that are industry standard. The staff not only fits right in, but they also contribute their knowledge and perspectives, making them a vital component of the programme.

      Software Development Review from Henrique Dubugras

      Services that had been slow or unavailable for weeks had to be brought back up. We must bring back our vital business role. After learning about our issue, the Closeloop project manager assigned a senior database specialist to address it. Our main programmer had a direct conversation with the database specialist of Closeloop after they listened to our problem and asked some follow-up questions. Within less than two hours, the solution to our issue had been verified and implemented.

      Software Development Review from Bill Rogers

      We occasionally utilize outsourced resources to increase our team's ability to satisfy the commercial demands of our clients. This time, my goal was to create and enhance the products we were providing to clients. Their engineers joined our own team to work on the project, creating MetaTrader-based software for our traders. They assisted us in creating and refining a suite of services that give our clients more functionality; up until that point, the solution had been erratic and unconventional. Their most recent endeavor was the development of an income trading module. We employed a scrum methodology with sprint deliverables and agile planning. Along with narrative points, we also used our in-house bug tracking application for project and task management. Everything was really accurate.

      Webman Technologies's Review Sourced from Google

      Sleepless Media did an outstanding job on our Shopify project. Their team combines creativity with deep technical expertise, making the whole process smooth and stress-free. They truly understood our brand, designed a store that looks stunning, and optimized it for performance and sales. Communication was always clear, deadlines were met, and they went above and beyond to deliver a result that exceeded our expectations. If you’re looking for a reliable partner for Shopify design and development, Sleepless Media is the perfect choice. Highly recommended!

      Barry Pinto's Review Sourced from Google

      Sleepless Media is the kind of web design agency that I've been wanting to work with for years. My company's website was in severe need of a redesign, and we knew that it was going to be a complicated project in terms of content migration, customizations, and attention to detail. I also needed a design agency that could work hand in hand with our SEO people. Fortunately I found Jon and team, who are not only extremely talented web designers but great listeners as well. Also a very patient team - we were far from a well prepared client in terms of having our site content ready to go, but they made the upgrade happen for us regardless. If you have been thinking about a redesign and need a Shopify partner that you can trust, this is your agency. Highest recommendation, and I plan on sending them all of our future web development business.

      Victoria Comeau's Review Sourced from Google

      I reached out to Sleepless Media after the company I originally chose to work with to transition from BigCommerce to Shopify did an awful job. What was supposed to be a three month project was now a year and a half nightmare. The team at Sleepless Media was so knowledgeable, transparent, communicative, and just amazing to work with. If I needed any clarification on anything, they didn’t hesitate to offer to hop on a call with me to make sure I knew what was going on. Every member of the team I have interacted with has been nothing but amazing. I can’t recommend Sleepless Media enough. The work they do is top notch, and worth every dollar. If you work with them, you know the project is going to be done and it’s going to be done exceptionally.
