      WordPress Review from Meagan Pate

      Singula Web Development Group redesigned our website from scratch and built it with WordPress. To start off the project, they looked at our site statistics and traffic and talked to stakeholders within our association to find out what our goals were. After that, they went straight to the actual development and design process. During this phase, they worked on our sites backend, adding our requested features that included integrating a management system. They also worked on the color scheme and other design elements. The quality of the website is great and fantastic. Plus, the management system they have integrated works really well. We have also received more traffic to our website since having them redesign it.

      Mobile App Development Review from Beranger Dumont

      Junkies Coder delivered an excellent mobile app for BPI Real Estate Poland, combining strong technical skills with a clear understanding of our business goals. From the start, they were professional, responsive, and focused on user experience. The app was designed with a clean, modern interface that made property browsing, filtering, and agent contact smooth and intuitive. Built using React Native, it launched seamlessly on both Android and iOS platforms, with features like advanced search, map integration, push notifications, and bilingual support. The team managed the project efficiently using agile methods, kept us informed with regular updates, and quickly implemented feedback. They also ensured strong backend integration with our property database and CRM. Testing was thorough, and the final app was stable, fast, and secure. Since launch, we've seen a noticeable increase in user engagement and property inquiries. Junkies Coder also provided great post-launch support, helping us refine features and monitor performance. Overall, they exceeded our expectations and delivered a product that added real value to our business. We highly recommend them for any mobile app development needs.
