“Delta Systems developed a mobile app for a catering company. This includes integrating reporting tools, a camera functionality, and a database for menu visibility and collecting student feedback and requests. The client launched their project before the beginning of the academic year, allowing chefs and students to use the app immediately. Delta's responsiveness, communication, and project management were exemplary.”

“Delta Systems developed a mobile application and a web-based database for an evaluation consulting firm. The app queries a patient list and then deploys surveys through a pin code on a device. The team has delivered on the client’s ambitious roadmap and stood out for their ability to build a genuine relationship. We’ve gotten to a space where we can clearly articulate what we need and know they’ll do their best to make it happen.”
