      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.

      Software Development Review from Dennis Temko

      Dreamers was the only firm capable of building my ambitious vision for HyperCite. They transformed an unprecedented concept into a patented, production-grade legal technology platform designed for fact-checking. This included help in product strategy, and leading UX, algorithm development, AI, database and cloud architecture, frontend and backend engineering, scalability, observability, CI/CD, deployment, and ongoing maintenance. They delivered two California product versions and a dedicated Arizona implementation integrated directly with the appellate court, where HyperCite has operated for more than five years. Today, HyperCite not only automates hyperlinks between legal briefs and cited records; its AI fact-checking system compares claims against supporting evidence, flags contradictions and unsupported assertions, and takes judges and attorneys directly to the underlying source. The result is faster, clearer, and more reliable judicial review, delivered through close collaboration with HyperCite’s leadership and the Arizona court CIO.

We never would have imagined would actually be possible We love the website tremendously and I'm confident that the website itself has brought us a lot of new business. I highly highly recommend anyone who's looking for a beautiful website to work with Jinny and her team. In fact, I've already recommended numerous friends to her.
