      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.

      Our goal was to build a scalable, robust solution based on cloud computing. The software should be able to offer multiple complex services online, including e-commerce and high-performance computing.

Their communication was excellent—always timely, transparent, and easy to follow—which made coordinating even complex project details effortless.Technically, Abdul and his team exceeded expectations. They delivered a high-quality, robust app that not only met but often anticipated our needs. Even with my busy schedule and frequent change requests, CMolds was incredibly flexible, adapting quickly without compromising quality or deadlines.What truly sets Abdul apart is his responsiveness and ongoing support. Any questions or issues were addressed promptly, with practical solutions and clear explanations, making the entire process smooth and stress-free. Their client-focused approach, combined with deep technical expertise and creative problem-solving, makes CMolds a standout partner for anyone looking to develop an app. I highly recommend Abdul Wasay and CMolds to anyone seeking a skilled, reliable, and exceptionally accommodating development teamThank you so much!

      So far so good. I am still waiting on an issue with Apple but I am excited for what they have created for my app idea. From Roman getting me started and connected with the development team to Safwan orchestrating the software, listening and making the changes I want. It has been a positive experience. They are flexible and do things in a timely manner. Can't wait until it finally gets released.

      The avatar pronunciation tool they built is mad. TTS with emotion and lip-sync so learners can actually see how to shape their mouths for English sounds. The avatar’s facial expressions carry the tone—it’s not just a flapping mouth. Our language students retention jumped 30%. No cap these folks understand the little things.

      Mr Garry's Review Sourced from Google

      We brought Litslink in to build RIV — a GPT-powered AI task planning assistant for our product management team. Before the engagement, our PMs were spending 30–45 minutes per request manually rewriting briefs into Jira tickets, and risk blind spots kept surfacing after deadlines had already slipped.Litslink designed a three-pipeline AI system covering task decomposition, risk prediction, and named entity extraction — all integrated directly with our existing PostgreSQL stack and Jira workflow. The NER layer now auto-fills 90%+ of date, tag, and assignee fields, which alone eliminated hours of repetitive copy-pasting across Slack, Notion, and Jira.The results were measurable: task decomposition is now 60% faster, and each PM recovers roughly 8 hours per week. The Scrum-based delivery was transparent throughout — two-week sprint demos surfaced edge cases early, and the team iterated quickly based on real PM inputs.Delivered on schedule and within budget. Post-launch support and prompt refinements have been proactive. Solid technical partner for AI-driven workflow automation.
