Concept open source team was able to complete our project within the deadline and budget we had set for this project. Since our experience was positive, I hired Concept open source team again for the 2nd version and now focusing on the 3rd version. I do have a good feeling with Concept open source team’s commitment, background, skill set, and experience.
