Some problems can only be solved with code, but others require end-user thinking. So Plavno developers remember that the whole goal is to solve problems — not only to write code. They thought about the problem from the restaurantants point of view.They developed a food delivery app with both customer and admim panels, which covers all the necessary functionality.

IT Outsourcing Review from Yana Romanovskaya

Plavno was creating profiles with pulling up a lot of information (clusters). Xunit-based scoring was used when setting up a .NET 2.0 project. Scoring for this format works similarly to Junit. The team extended the products by adding features, fixing bugs. This development can change cluster parameters, cluster management system (current state of the object), customize vectors that lead to this cluster and make predictions.

Staff Augmentation Review from Sergey Novik

Were developing an internal image processing tool for our design team and needed two machine learning engineers, since our core developers were busy with other client projects. We required extra hands familiar with Python and computer vision, so after a developers market review, we hired them from SumatoSoft.The SumatoSoft developers joined our team and were able to swiftly adapt to our workflows, which resulted in them delivering the working models well before our hard deadline.Communication was straightforward throughout the engagement. We had video calls and exchanged brief text updates on a weekly basis. The delivered code is clean, and pull requests are well-documented.I appreciate that they pushed back on a few of our initial architecture ideas. They challenged our original approach and proposed a better method for handling the model weights. We plan to bring them back for the next phase of development.

Product Design Review from Chris Milner

UXReactor helped us with a UI/UX research process, which included in-person interviews where they walked users through unboxing, connecting, and using the features of our smart air conditioner. From there, the team took the findings and produced a report for us to make improvements to our app and increase our activation rates. In addition to the report, UXReactor also redesigned some parts of our app using Figma.The project required a very iterative process, so we required more than one discovery call to get started. In fact, they didn't just work with me; we also integrated our consumer marketing insights team to identify participants. We also collaborated with them to figure out how to recruit the right users based on our target customer profiles.Additionally,UXReactor recruited participants for us, going through their database to find actual users. Then, they brought a researcher and a designer to interview all the participants on-site in their location. That was actually a challenge because we're a remote team, but we needed a physical location to show the actual air conditioner to the participants.After the interviews, UXReactor worked with us to go through the results and the report's structure. We had multiple revisions to ensure that we were pulling out the insights I wanted to find on it. After the report was complete, they actually delivered it to our overseas team, doing a presentation that included the insights and recommendations.

The objective was to create a safety release which would activate at certain weights and fit into an already existing design. Porticos was able to create a strong, lightweight and reusable buckle which fit perfectly into the design both functionally and visually.

We've worked with the Dirtverse team on the branding for both North House and, more recently, Norcu. We gave them pretty much free rein creatively and were blown away by what they came back with every step of the way. They really understood what we were trying to achieve, even when we couldn't necessarily put it into words ourselves. They're creative, easy to work with and genuinely great at what they do. We couldn't be happier with both brands and would highly recommend the Dirtverse team!
