Software Development Review from Michael Meyer

We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!

Web Development Review from Anastasiia Cherednichenko

We worked with Stubbs on a project for a shared client. Our team was responsible for the web application layer, and they handled the blockchain backend. The integration points were clear and well-structured, which made our side of the work manageable. Communication was straightforward throughout, and we didn't run into any major blockers. There was a short alignment phase at the beginning where we had to figure out how the two parts would connect, but once that was sorted things moved without issues. Overall a solid team to work with on a technically split project like this.
