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!
