      Software Development Review from Emma Bowers

      John Tomblin has served as the software architect and Chief Technology Officer for our software startup, LabPair, for the past two years. During this time John has played an essential role in developing the LabPair software, helping us hone our business model, and plan our launch strategy. I have been delighted with John's services and look forward to our continued partnership. John enjoys a high degree of success as a developer because he is able to engineer software solutions for a variety of marketplaces, no matter how complex or niched. In additional, he has a highly orchestrated, efficient, time- tested process that he uses to scope software projects and get them programmed to clients' specifications. I have been especially appreciative of how John and his team have been both forthright and accurate in estimating the time and cost associated with project development. By far, my favorite part about working with John is his jovial personality, can-do attitude, and excellent communication skills.

      Software Development Review from Thomas Canale

      In 2022, I realized that I needed to find a software development firm capable of designing and developing a SaaS application that would serve the real estate community's need to create reliable, usable, Competitive Market Analysis (CMA) reports, but do so in such a way that also reduced the creation time by as much as 95%. After meeting John and his team, and talking for several weeks about my project, I knew instantly that Data Titan was the right company. Not only were they attentive to every detail of the project, but they also remained vigilant with communications, managing change orders, and keeping to the exact time schedules set for the two-year project, and its numerous phases. Additionally, John's company used 'Scope Atlas', their company's software development application system, to design every screen before any programming work. Having now been through a two-year development process, I realize this project would have never launched without 'Scope Atlas', John's leadership, his senior team, and most importantly, his considerable expertise and insight in the software development sector. I wholeheartedly recommend John and his company for any software or mobile app development project you may be considering. Thank you.

      Software Development Review from Kara Peterson

      Have you ever had a dream? Have you envisioned greatness? This is who I am, I had the idea, but it was just out of my grasp. John Tomblin is in the business of making your creativity and genius a reality. When I first reached out to John, I thought I was on one track. I have a habit of seeing the end, but all of the details are distractions and I had not given them any thought. I was completely unaware of the scope of my project. John did a year long scope and sequence with me, that turned into consulting. He showed me that there is so much more than the end product. I have worked with technology companies in the past and they do one thing really well, they develop technology. John looks at the project holistically. From when the consumer/customer first engages with your product, to how they will actually purchase the product, to the ease of use of the technology, to the performance of your product, to the marketing - how will you first find these customers, and so much more. John is detail oriented and very organized. Nothing slips past him because of his methodology with his wireframes. He holds weekly meetings to make sure the client (me) and he have both done our "homework" to move the project forward. The meetings also ascertain that we are both on the same page about the project. Working with John is a pleasure; I look forward to our weekly talks. I am certain that he is "on my side" and is looking out for my best interests. The world has gotten very small and it is easy to find someone to build your product. However, it is not easy to find someone who will listen to your dream, help you reach it, look out for your best interests and whom you can put complete faith in.

I know nothing about computers and I'm sure 6-year-olds these days have better knowledge of computers than me. lol but overall, I'm grateful he explains things to me so I can understand and moving forward I know what to do. Also, he has a great personality.

      I have experience working with the rollout.ai team prior to their official launch. I can vouch for their breadth and depth knowledge in this space as they helped me navigate IT issues that were beyond my level of comprehension. They were quick to identify, isolate and find a solve that didn't require me to spend the capital that I thought was needed to remedy my situation. Above all, the team was great to work with and clearly explained the cause and how to mitigate in the future. I'd be happy to work with them again.

      My office network crashed on Friday. VQIS was there the same day to diagnose the problem. They got it up and running the same day, and recommended a couple upgrades to insure it would not continue happening. They were out the following Monday to repair/replace the equipment. A+ for these guys, all of them know what they are doing and they had me up and running within hours of the initial phone call. THANK YOU VQIS!

      Top notch all the way! Professional yet personable. Extremely good at what they do (Mac or PC) and they explain everything in a way I can understand. VQIS does remote monthly maintenance on my work laptop (windows), as well as takes care of my family’s non-work iMacs when we have issues. I trust them so much that I’m willing to drive an hour and a half to bring them my computers if they need to fix hardware issues. Fast turn around with status updates along the way. All with a friendly attitude and a great sense of humor, which is always a plus!
