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.

Global business segment growth is requiring technology to keep up with the increase. Our platform is designed to be scalable and able to be implemented across several nations. We collaborated with Closeloop Technologies to work with our staff in order to scale up the programme.An whole agile team is provided by Closeloop Technologies to participate in our programme. At first, we gave them the data in hopes that they would aid in our execution. They have combined Spring Boot, JavaScript, and AWS cloud technologies.The platform is a value stream and full-suite insurance lifecycle. It is an internal iterative software programme.Working with Closeloop Technologies is simple. They pick up new roles rapidly and possess agile team abilities that are industry standard. The staff not only fits right in, but they also contribute their knowledge and perspectives, making them a vital component of the programme.

Software Development Review from Henrique Dubugras

Services that had been slow or unavailable for weeks had to be brought back up. We must bring back our vital business role. After learning about our issue, the Closeloop project manager assigned a senior database specialist to address it. Our main programmer had a direct conversation with the database specialist of Closeloop after they listened to our problem and asked some follow-up questions. Within less than two hours, the solution to our issue had been verified and implemented.

Software Development Review from Bill Rogers

We occasionally utilize outsourced resources to increase our team's ability to satisfy the commercial demands of our clients. This time, my goal was to create and enhance the products we were providing to clients. Their engineers joined our own team to work on the project, creating MetaTrader-based software for our traders. They assisted us in creating and refining a suite of services that give our clients more functionality; up until that point, the solution had been erratic and unconventional. Their most recent endeavor was the development of an income trading module. We employed a scrum methodology with sprint deliverables and agile planning. Along with narrative points, we also used our in-house bug tracking application for project and task management. Everything was really accurate.

WordPress Review from Tu Loan Huynh

Stuntcoders helped us to build our new website via WordPress, including an online shop. We delivered a complex design in Figma; they did all the development and technical stuff. They were always keen to meet our wishes and needs. They also implemented a bunch of Advanced Custom Fields for everywhere we wished so. They worked overtime and night shifts to meet the delivery date and were always honest when they did something wrong or misunderstood our wishes. I could always tell they wanted to deliver an excellent end product even though the project exceeded budget because we needed much more than expected. Stundcoders not only developed our website, but they were in the project with their entire investment and always had significant inputs. Communication is also on a great level since they assigned a lead from their side for our project. I would 100% recommend this company.

wdi took the vision we had and turned it into something even better. They built this incredibly detailed app that lets users filter hotels based on things like airport transfers, car services, or other specific amenities. Travelers can also quickly spot deals or limited-time offers with just a glance.One of the coolest parts is how the app keeps guests updated when theyre checked into a hotel - whether it's on-site events or nearby activities, theyll get notifications straight to their phone. The feedback system they added is a game-changer. Guests can send questions or share thoughts right from their rooms, and they get notified the moment theres a response.

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.

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.
