About Justin Matthews
Software architect, application developer, and leader.I believe the most scalable engineering organizations are built on autonomy, trust, and clarity of purpose.As an engineering leader, I’ve shaped teams that thrive in uncertainty by combining technical excellence with people-first leadership. My philosophy is influenced by both research and lived experience, including:* David Marquet’s Turn the Ship Around – empowering teams through decentralized decision-making.* Kim Scott’s Radical Candor – building cultures where feedback fuels growth.* Amy Edmondson’s research on psychological safety – creating environments where innovation and risk-taking flourish.* Adam Grant’s work – driving resilience and adaptive organizational culture.* Napoleon Hill’s Outwitting the Devil – cultivating focus and freedom from fear in decision-making.In practice, this means I foster autonomy and ownership in engineering teams, align execution with strategy, and develop future leaders who can scale both technology and culture. My passion is not only building great products, but building the teams and systems that make them possible.Interests: Products based on AI Agents and Systems. Large Scale software. Real-Time Communications, Distributed Systems, Web Services, Machine Learning, Engineering fundamentals (lifecycle, security, SRE, Observability, Deployment, Testing)
