      iPhone Review from Gabriel Sabadin

      We engaged SolveIt to develop a minimum viable product (MVP) app, including a user-friendly iOS design, an artificial intelligence (AI) model, and a monetization strategy while ensuring General Data Protection Regulation (GDPR) compliance and preparing for future integrations. Despite a tight deadline, SolveIt delivered the app on time and efficiently handled beta-testing within three months, allowing us to gather feedback and launch successfully. We acquired our first 1,000 users within a month of launching the app. SolveIt's team communicated effectively, addressed issues proactively, and maintained a high level of autonomy, bringing diverse expertise that greatly benefited our project. We appreciate the agency's dedication and professionalism.

      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.

      Mobile App Development Review from Mark Joy

      Dima S. responded to one of my job postings on Upwork for creating an audio-related application. He explained the estimated cost of developing such an app, and advised that it would be much more costly than I had anticipated. I was not familiar at all with the costs associated with developing apps, so his explanation was very helpful.He saved me money by going above and beyond to research existing apps that provided similar functionality to the requirements I was seeking. He also found instructions for using native Apple settings for audio that would solve my problem. The settings he found even allowed import of an audiogram that I had gotten at the audiologist for my specifc problem.Though he did not end up developing an app for me, Dima saved me a ton of money by spending his time to research possible existing solutions which I had not found during my own search.I would highly recommend Dima for his level of care for projects and his customers.

      Working with CitrusDev was very comfortable and convenient.CitrusDev developed a website (WordPress) for me with the services I provide to my clients.Since I have a shortage of time, it was important that the team did not need my constant involvement in the process.After discussing all the details, we met a few times to decide on further actions and make corrections.The work format was convenient and clear. And most importantly, it was flexible.The team responded quickly when changes were needed and gave advice for better results.I am happy with our joint project and want to thank CitrusDev for their professionalism and ease of work.Thank you.And I recommend them.
