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.

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.

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.

Flutter Development Review from Undisclosed

The company has a salesman who overpromised, but once the project started, he was never found to address the underdeliver. Since the first brief, I made clear our products two main selling points. Two years after, I have had to learn some code to look under the hood and discover a half-baked and improvised "solution". Now, I ended up with an incomplete product that fails to deliver the two main functions I requested (and was promised). On top of that, there is a lack of order in terms of naming, cleanliness, and hierarchy. I cant recommend them.
