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.

Software Development Review from Elizabeth Sheehan

Our main goal was to update our web presence to more accurately represent our proficiency in IT consulting and services. Our prior website was disorganized, had poor performance, and failed to adequately convey our expertise in customer relationship management (CRM), customer communications management (CCM), and content management systems (CMS). We required a highly functional, aesthetically pleasing, and scalable website that could captivate users, offer smooth navigation, and blend in seamlessly with our current technology stack.They have perfect attention to detail. They took care of everything, from making sure the font and color scheme matched our corporate identity to making every user interaction as efficient as possible. The outcome was a website that serves as a potent instrument for business expansion in addition to being aesthetically pleasing. They were always helpful and quick to respond when we had questions after the launch.

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.

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.

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.

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.
