"Daniel and team were fantastic. They provided great insights that informed our direction even before we awarded the contract and they executed with skill, speed and great communication. Our project was a fairly simple Bluetooth feature to an existing app but they were creative in thinking of alternatives when we did encounter some unforeseen challenges."

"Daniel is an amazing and thoughtful application developer with a deep understanding of technology and business processes. He takes the time to truly understand a problem and then finds innovative ways to solve them with technology. The app he created for us was not easy - utilizing a combination of machine learning / AI, document capture, in-app subscription systems, cloud storage, and web publish - all through an iOS App! Further he directly managed the app UI/UX design with our freelancer so that our customer experience and on-boarding was seamless and easy. In the end, the app he created for us exceeded our expectations!"
