About Me
Bryce E. has been a passionate iOS Developer since 2017, starting as a self-taught freshman in computer science. His running journey began with a 5K in January 2019 and culminated in completing the Memphis Marathon that December. By October 2021, he became the youngest 50-mile ultramarathon finisher in Memphis. Along the way, he used his Apple Watch health data—combined with Python and data science skills—to realize his training aligned more with endurance than elite-speed racing. That insight led him to build Stamina Bar, an app that transforms complex health metrics into simple, actionable insights. It’s designed not to overwhelm or obsess, but to guide users toward sustainable growth. Bryce also volunteers with Girls on the Run (GOTR), where mentoring young athletes has fueled his passion to inspire the next generation through thoughtful technology and movement.
