Cerner Corporation needed to quickly develop a suite of iOS healthcare apps and wanted help, so they commissioned their training consultants at About Objects  to find these Objective-C veterans, NeXTSTEP warriors of old. ZION was brought in and helped develop reusable Cocoa Touch components for use across the suite of healthcare apps, while mentoring junior engineers. During this effort, ZION was commissioned to enhance and contribute to an open source bug management system developed in Ruby, and add full-stacktrace iOS crash log symbolication. ZION also developed a rules-based notifications component and helped Cerner prepare for “meaningful use” government healthcare certification. The year-long iOS consulting effort was a huge success.

ZION was chosen to develop significant enhancements to myCigna iOS app, including a full redesign for iOS 7 and validation through iOS 8 betas. ZION also replaced legacy code with iOS localization, and added auto layout functionality to meet the need of larger iPhones. ZION also formalized and documented a mobile team development process including coding standards; co-located the iOS team for better collaboration; procured dual monitors for team to boost productivity; initiated and coordinated the transition from Subversion to git, working with DevOps; and instituted and lead a full Agile development process. ZION also prepared and presented pros/cons of native vs. hybrid mobile apps, and won consensus among product stakeholders to drop legacy iOS support in myCigna. Millions of Cigna health insurance members use the app every year to manage their healthcare and Rx.

A health-tech startup focused on better outcomes for hip and knee replacement patients as well as healthcare payers, was in the process of early stage acquisition by Rally Health, Inc. Founders of the health-tech startup brought ZION in to maintain the startup's flagship iOS patient app, while also looking to ZION to help staff and build the tech team to rebuild a new iOS app for patients and providers under the new Rally Health ownership. As part of the acquisition milestones, the health-tech startup would need to build the new iOS apps with tighter enterprise grade security, higher unit and automated test coverage, and integrate into Rally's existing enterprise-class healthcare tech stack.  ZION leveraged its deep partner network to bring in seasoned iOS consultants as well as interview and assist in the hiring of new Rally iOS talent. The team, let by ZION's principal consultant, David Ferrero was able to simultaneously maintain the legacy health-tech iOS app, and build from the ground up, a new Rally Recover iOS app for patients and the companion app, Rally Recover iOS app for providers. The team lead by David, built reusable iOS components for networking and interactive patient-provider messaging. The team reached the high unit and automated test coverage requirements of Rally, and passed the independent healthcare and enterprise-grade security audits. The health-tech startup successfully completed the technical milestones as laid out in the acquisition document. 

As the new year approached and pressure to ship the first healthcare app mounted, Aetna Digital reached out for help. In short order, ZION quickly added location-based search to allow Aetna health insurance subscribers to quickly find in-network doctors and healthcare facilities. This is the most widely used feature in the app.

Vertex Pharmaceuticals, Inc. hired ZION to assist in ongoing iOS development of their enterprise iPad app for their sales team. In addition to ongoing iOS feature development, ZION added time-critical updates to support Healthcare Provider COVID protocols, as well as building a mission critical feature for the Vertex Sales team. This required ZION  to collaboration closely with the Salesforce engineers, designers and product owners. The features were delivered on time and received with much praise.
