      5.0

      Cross-Platform Review from Awital Ifrah

      Masa came in with a pretty loose idea and AppMakers helped turn it into something solid. What I appreciated most is they didn't overcomplicate it or try to make it into some giant monster platform. They listened, asked smart questions, and helped us focus on what would actually matter for alumni and current participants. The end result felt thoughtful and realistic. I'd definitely work with them again.

      Startup Review from Moishi Stern

      We create live events. We wanted a site that shows what we do without making people dig. AppMakers listened, trimmed the fluff, and gave us pages that read fast and look good on a phone. The quote form asks the right things and our team can update galleries without calling a developer. They stayed on schedule and answered messages the same day. The whole process was calm and clear. We already see better inquiries. It feels like a real upgrade, even before the full rebuild.

      5.0

      IT Services Review from Rhosel Dayrit

      My top 3 things about TruAdvantage:1) The single biggest benefit is Security. Since we are a medical field office, our primary concern is securing patient’s files and account information. Second would be backup. Since most of our work is online it is important to have back up on all files electronic and non-electronic.2) Customer service is excellent and dealing with our issue at a moment’s notice is beyond expectation.3) I would highly recommend for them to try it out. they will see a big difference in the proficiency of work, the team itself and the care to their customer’s need.

      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!

      One of the largest and fastest growing IT services providers in the country. Knowing I can call the support desk 24/7 for solutions, when we deal with real deadlines with real consequences, makes a huge difference for me as well as our staff.And, for the most part, we don't have to call the support desk because everything works. The only times I have to reach out is when we hire a new person, or add a new service or license. They are very pro-active and results oriented.

The design style is great, cleverly combining the mountain trend, using lush trees and spacious grasslands to integrate the residential area with the natural landscape. This is a very ideal residential area.
