      Angie Tromley-Morales, PMP CEO at House Caddy
      5.0

      Mobile App Development Review from Angie Tromley-Morales, PMP

      We hired Empat to design and build the MVP of House Caddy, a household management app that keeps receipts, warranties, manuals, and repair history in one place, with reminders for expiring warranties and maintenance. The product also helps homeowners prepare a full digital home history for future property transfers.Empat delivered end-to-end work: discovery, UX/UI design, Flutter mobile development, and a Python backend. They implemented a clear flow where users first create home appliances/systems and then attach documents and repairs to each item.A major highlight was Empats AI expertise. AI features simplify the entire user journey by auto-filling appliance details from photos/docs/links, assisting with utility provider setup, and importing contacts to speed up adding contractors. This reduced manual input and made onboarding fast and intuitive.Communication was excellent, with proactive brainstorming, clear sprint updates, and on-time delivery. The MVP is market-ready, early feedback is very positive, and Empat proved to be a reliable, product-driven partner with strong mobile, backend, and AI capabilities.

      IT Services Review from Anna Krebs

      Mitrix Technology partnered with Creative IT to enhance an existing case management system. They augmented Creative IT's team with a Frontend Angular developer, who contributed to a range of improvements, including streamlined navigation, integrated case addition, enhanced search functionality, document viewing capabilities, trial schedule tracking, planner establishment, scheduled event edit monitoring, code library selection, and application structure shaping. These enhancements resulted in a significantly improved case management system that is more performant, usable, and maintainable. Mitrix Technology's expertise, team augmentation approach, and client-centric focus made them a valuable asset to the project. We strongly recommend Mitrix Technology as a reliable and innovative IT services provider to businesses seeking to achieve their software development goals.

      Staff Augmentation Review from Dzmitry Novikau

      I worked with Kernelics on a crypto project where we needed help with both design and development. From the beginning, the team was easy to communicate with and clearly understood what we were trying to build.The designer improved our initial ideas by making the user experience more intuitive. They suggested better ways to structure the navigation and user flow, which helped reduce friction and made the product easier to use.We also brought in one of their developers, who worked alongside our existing team member. They collaborated well, completed the work on time, and handled some challenging parts of the exchange functionality without any issues.Overall, Kernelics delivered quality work, stayed within budget, and were professional throughout the process. I’d recommend them to others looking for a reliable design and development partner, especially for crypto or fintech projects.

      Stsiapan Kolesau CEO at Module Technology

      Web Development Review from Stsiapan Kolesau

      I CEO at the construction company specializing in modular buildings and their components. With years of experience and multiple projects, we decided to expand our online presence beyond our two existing landing pages. We needed a corporate portal to showcase products, manage content easily, and dynamically calculate product costs.On a recommendation, we chose Kernelics, and their organized approach and clear task division impressed us from the start. They began with an in-depth analysis of our needs and a competitive review. For the design, we requested a minimalist style, and the results were spot on, requiring only minor tweaks to meet our expectations.For development, Kernelics selected React, Next.js, and TypeScript, with Strapi for the admin panel. They also integrated Google Sheets to handle dynamic price calculations, enabling instant updates on the site by simply modifying the spreadsheeta feature weve found incredibly useful.Now, two years later, the portal continues to support our growth, and were planning new developments for our main site.Kernelics stood out for their transparent approach and professionalism at every stage, and I confidently recommend them to anyone seeking a reliable web development partner.
