Summary
🎓
Top SchoolStephen Ma is a pragmatic enterprise architect and engineering leader with 8 years of senior leadership experience shaping technology strategy across retail, pharmacy, and healthcare. Currently Head of Enterprise Architecture at Ulta Beauty and an advisor to a stealth startup, he has driven large-scale transformations at Walgreens and CVS Health—building enterprise technology landscapes, API standards, data governance, and architecture communities that shifted culture toward tech-centric collaboration. He combines hands-on engineering roots (Java, platform architecture, CI/CD) with a knack for organizational change: founding Architecture Assembly forums, Architecture Decision Record processes, and innovation incubators like hackathons and engineering accelerators. Stephen is fluent in translating business capability models into actionable roadmaps—reducing technical debt, unifying identity, and enabling reusable platform patterns across omnichannel ecosystems. Based in Texas with a CS master’s from Boston University and a physics BS from Michigan, he balances rigorous technical thinking with practical delivery. Outside work he’s an open-source enthusiast with a famously blunt motto against mediocrity—he enjoys building community and the occasional drink.
