AI Development Review from Oleg Sotnikov

Diffco built a complex, production-grade AI agentic system and backend for our client's fintech platform owning architecture, AI/ML components, and AI agents in a security- and compliance-sensitive environment. They delivered on time and within budget, communicated proactively, and operated like part of our own team, taking ownership and suggesting better solutions throughout. Deep AI/ML and senior backend expertise. We'd happily work with them again.

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.

Mobile App Development Review from Gina Levy

Both the developer and tester have exceeded expectations. Their performance is excellent. Together they eliminated bugs, introduced new features, and ensured that the app is working without problems. Previously, we had many complaints in the app store. Since working with this developer and tester, these complaints about the app functioning and bugs have disappeared.The time zone different is sometimes challenging, since we are in California and they are in Europe.

Web Development Review from Beata Twardowska

The team was committed, helpful, easy to collaborate, and most importantly professional and skilled. They knew perfectly well what solution we needed based on the goals we described to them. What we value the most is good communication. We were kept informed about the progress of work and we got answers to all of our questions.Our clients love the new design and now they have even better understanding of our services. We have also received many positive opinions from industry specialists.We are very satisfied with the cooperation and its results. There is not much to improve. When we first launched, we found the animations a little too fast and we had to adjust them.Every challenge has been met. Our new website is safe (0 attacks after launch), fast – despite using so many animations (page speed insight analysis showed 86 on the desktop and almost 60 on mobile), and both user- and seo-friendly.

Web Development Review from Ollie Maitland

We were particularly impressed by Naturaily's proactive and collaborative approach. They went beyond simply executing our requirements by taking the initiative to understand our underlying business objectives and offering valuable insights and recommendations. Their deep technical expertise in headless architecture, coupled with their commitment to delivering a high-quality solution and their strong communication skills, made them a truly unique and valuable partner.Our marketing team now has the independence to test and refine content thanks to Naturaily. The CMS overhaul and testing framework have made it easy to optimise our user experience without needing developer support. We can now collaborate more effectively than before, which increases productivity. We have also observed improved website performance, indicated by faster page load times. The successful deployment of a modern technology stack also provides a scalable foundation for future growth.They delivered on every performance goal while keeping us informed and building a platform that puts testing and innovation first. Naturaily's project management was highly effective. They consistently delivered items on time and were very responsive to our needs and feedback throughout the project lifecycle, demonstrating a strong commitment to our success.They guided us through every step of our platform migration with exceptional care and expertise. We're really happy with how everything has gone, and our collaboration with Naturaily is actually ongoing.

Web Development Review from Polina Medvedieva

High skills and responsibility make Naturaily a reliable, trustworthy, and professional technological partner. They grasp even the most nuanced details of our requirements and are effective in managing project needs.We can count on them even with the tiniest issues as the developers we work with are attentive, good communicators, and always stay in touch. They’re versatile enough to comfortably connect and engage with both technical and non-technical staff.Naturaily consistently delivers tasks and project stages on time, and we’ve seen a noticeable reduction in website bugs as a result. The great thing is that their team brings valuable proactive insights, thoughts, and suggestions to the table.Naturaily helped us drive the website project forward with a clear understanding of our strategic goals and operational needs – all while in a specific technological environment. They’ve been highly operational and creative whatever a challenge or change came.Naturaily used Jamstack architecture (Vue.js and Nuxt.js) to improve our website’s front-end interactivity and back-end efficiency. This upgrade laid the groundwork for additional features, crucial for the site's evolution and business growth. From the very beginning, they’ve supported us with great dedication and skillfulness, all while minimizing the need for continuous technical oversight.

Mobile App Development Review from Tim Nguyen

Warning: Avoid Apptunix (apptunix.com) If you're considering hiring offshore developers, especially from India, I want to share a warning about Apptunix (apptunix.com) and its CEO. My company worked with them on a development project, investing close to $40K, only to have them hold our code hostage and demand more money before releasing it.We entered into the project with clear expectations and milestones, but as we progressed, Apptunix consistently delayed, under-delivered, and eventually refused to hand over the work we had already paid for unless we agreed to pay more. This kind of behavior is nothing short of extortion. It seems like their CEO and leadership are more interested in squeezing money out of clients than delivering quality work.Beyond the financial frustration, the skill level and talent from this team were not up to par. The development work was substandard, full of bugs, and lacked the quality we expected for the investment we made. I strongly urge anyone considering offshore development to do your due diligence or, better yet, reconsider offshore development altogether, as the experience in some regions, particularly India, seems to be in decline.
