Top SchoolJustin Bergen is a Senior Software Engineer with 14 years building high-quality mobile experiences, specializing in iOS apps for health, fitness, medical devices, and connected hardware. He combines hands-on engineering with technical leadership—leading teams, mentoring engineers, and architecting BLE-enabled apps for clinical trials and consumer wearables. As a founder he scaled Shopify SaaS products to handle Black Friday traffic, and as a consultant he helped UNICEF KidPower earn major recognition while rebuilding its BLE stack and delivery processes. Comfortable across UIKit and SwiftUI, Justin has repeatedly modernized large apps and developer workflows, and he brings a practical systems mindset from early embedded and test-automation work. Based in Colorado Springs, he blends entrepreneurial drive with decades of product delivery and device integration experience that few mobile engineers accumulate.
