We partnered with Diffco for a comprehensive software development project aimed at delivering a mobile application and backend system for our client.

They handled everything: UI/UX design, backend architecture, API integration, and deployment. After the launch, they continued to support us with maintenance and performance optimization.

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.

Were very satisfied with the outcome and would definitely recommend Empat to anyone looking for a reliable software development partner.

UI/UX Design Review from Wladimir Wolinski

Communication was smooth either through our teams communication channel or with the project manager via email. We were in daily contact with the UX/UI designer in form of dailies or when we had to clarify some questions. With the project manager, we had a short conversation every 2 weeks to clarify all possible questions. We personally love to work in a very process-oriented way. Because when we understand how to do something, we usually know how the end result can look like. With Digis, we also had the feeling that they knew what they were doing and how to do it. Every next step was planned from the beginning. If something didn't work in line with our processes, we could readjust it. We were basically satisfied with everything.

Were developing an internal image processing tool for our design team and needed two machine learning engineers, since our core developers were busy with other client projects. We required extra hands familiar with Python and computer vision, so after a developers market review, we hired them from SumatoSoft. The SumatoSoft developers joined our team and were able to swiftly adapt to our workflows, which resulted in them delivering the working models well before our hard deadline. Communication was straightforward throughout the engagement. We had video calls and exchanged brief text updates on a weekly basis. The delivered code is clean, and pull requests are well-documented. I appreciate that they pushed back on a few of our initial architecture ideas. They challenged our original approach and proposed a better method for handling the model weights. We plan to bring them back for the next phase of development.

The time difference between my office in eastern USA and theirs in Moravia worked well, as we could meet at their afternoon/my morning and I had the rest of the day to deal with back end or questions they might have. Their professionalism and competency were impressive. I will continue working with them, for years, I hope, in maintenance mode or when we need to expand features.
