Safe Queue in action: Another Call for Code deployment in the field

Safe Queue in action: Another Call for Code deployment in the field. Open source-powered solution developed for COVID-19 response is keeping customers safe at small businesses like Waffle Cabin.

Now that we’re in our third year of Call for Code, I’d say one of the most remarkable things about the program is its constant capacity to surprise me with both its broad reach and agility. Call for Code unites hundreds of thousands of developers to create and deploy applications powered by open source technology that can tackle some of the world’s biggest challenges. Safe Queue is a great example of that, and our eminent judges recently named Safe Queue one of the top five solutions in this year’s Call for Code Global Challenge. Safe Queue was created by a single developer in Los Angeles, Dave Chura, who happened to hear about Call for Code while watching a video from Lady Gaga on his local evening news.

Dave was inspired by Lady Gaga’s call to action and decided to contribute his technological know-how to help support his community’s reaction to the COVID-19 pandemic. That’s the fortuitous origin story behind Safe Queue, a solution to replace physical lines at shopping centers, small businesses, and polling places with on-demand virtual lines, to support a safe way to manage entry during COVID-19.

Back in May, Safe Queue was recognized as part of Call for Code’s accelerated COVID-19 submission deadline, and since then my team and I have worked with Dave to strengthen his solution and incorporate feedback from users in a variety of organizations. Safe Queue uses GPS location data to create a virtual queue of those within 1000 feet of a location, allowing employees to control the queue digitally, and validating entry with a randomly generated QR code for each customer. This solution builds on IBM Cloud Foundry for web app hosting, HERE technologies for geolocation, Twilio for SMS messaging, and IBM Cloudant to store geospatial data.

After several development sprints working with Dave and IBM developer advocates to further develop Safe Queue, I’m excited to share the results of how it’s being used by small business employees and customers to keep them safe and reduce wait times during the pandemic.
