Chop Dawg Reviews & Testimonials

Web Development Review from Jimmy Caldwell
Chop Dawg was the strongest development team I’ve worked with in 18 years of software implementation. They took our complex AI-powered senior placement platform and turned it into a functional marketplace with dashboards, business rules, CRM integration, and an AI assistant. The team listened, adapted, communicated often, and treated our vision with real care. The handoff had a few gaps, but overall, they delivered exceptional work.

Design Services Review from Nathan May
Chop Dawg delivered wireframes, high-fidelity screens, a logo, and Figma files while keeping each week’s work clear. They felt like part of our team, brought fresh ideas, and pushed back when needed. The experience was strong overall, though a more detailed final review would have been helpful.

Web Design Review from Anonymous
Chop Dawg turned our early idea for a visual polling and decision-making platform into a prototype we could confidently share with others. It made the product much easier to explain, gave us something real to test with users, and supported more productive investor conversations. The work also helped our team get aligned on the product direction, development scope, and MVP roadmap. Their team was responsive, organized, and easy to work with throughout the process.

Mobile App Development Review from Tanyaradzwa Man'ozho
Scalacode has created a mobile application for iOS and Android. We initially had enough; the iOS app had been developed, so Scalacode reoptimized it and improved its performance. On the other hand, theyve built the Android version from scratch as a new application.Weve just launched the product, and the app works really well; its much faster performance-wise. Moreover, the product is more responsive, and our customers are happy.

Software Development Review from Candice Claassen
Scalacode has designed and developed my mobile app for iOS and Android. After signing the contract, I sent the team prototypes of my idea and vision for the app. Then, Scalacode started the development phase using React Native and Flutter, as well as Figma for design. The app is technically completed, and Scalacode is working on a couple of things. After launching the app, Scalacode will provide maintenance for a year.

Mobile App Development Review from Mila Banerjee
We started with a discovery phase with Scalacode, lasting 34 weeks. During this time, we discussed my app's features, design, and required process flows. It was an insightful and valuable phase.Afterward, Scalacode provided a quote for app development, and since they did well during the discovery, I chose to proceed with them.Scalacode has since developed the app from scratch for both iOS and Android, using Flutter for iOS. We've been collaborating on ongoing development for almost three years. Although the app isn't live yet, I know Scalacode has successfully worked on several apps for prominent companies. Based on their work so far, I'm confident in the quality, which has been excellent, and I have no complaints.

Web Development Review from Pete Herbst
We worked with Cidersoft to port our main website from Drupal 7 over to Next.js and a custom CMS backend. This was a heavy lift and they were instrumental in helping us accomplish the website launch on the new tech stack in the timeline we were looking for. They are responsive to changes in requirements and goals while also providing good feedback if they know of a better, more appropriate way of doing things. Pleasant to work with, good people. Overall, big thumbs up, would recommend.
