Summary
👤
SeniorDemetrius JOHNSON is a veteran technology leader and CTO with over three decades of software and business experience and 15 years of recent hands-on product leadership. He’s built and scaled high-traffic, revenue-driving web platforms (collectively serving ~600M users and $3.8B in sales) while also founding and shipping clinically regulated software-as-a-medical-device and AI-driven therapeutic prototypes. Equally comfortable writing foundation code as mentoring teams, he has led cross-functional orgs from NeXT and enterprise systems to modern React Native, Node.js, and cloud-native architectures. His work blends product, research, and regulatory rigor—authoring provisional patents, running clinical trials, and translating translational science into production software. A passionate instructor who’s mentored 150+ engineers now at top tech firms, he quietly combines deep systems craftsmanship with a founder’s eye for market-changing product bets. Currently cofounding a stealth legal-tech startup, he’s focused on reinventing immigration workflows using the same pragmatic, research-informed engineering approach.
