About

I’m a Staff-level Software Engineer and Tech Lead with 16+ years of experience leading product-critical systems at scale. I specialize in authentication, identity, and distributed systems within product organizations — owning ambiguous, high-risk domains that sit at the intersection of user experience, fraud prevention, compliance, and reliability. At Cash App, I led the evolution of Cash's authentication system into a modular, cross–business-unit platform, improving login success rates, raising SLO compliance, and reducing support load through systemic improvements in access controls and risk enforcement. I partnered deeply with Product, Risk, Compliance, and Security to balance growth, regulatory requirements, and user trust. Previously, I’ve: - Led Enterprise identity initiatives at Loom (SAML SSO, SCIM, audit logs, data retention) during rapid growth. - Shipped marketplace automation systems at Uber Eats eliminating large-scale manual workflows. - Improved core infrastructure and reliability at DigitalOcean and Medium. I’m most effective when: - A system needs to scale without breaking product velocity. - Technical direction lacks clarity across teams. - Risk, compliance, and user experience are in tension. - Senior engineers need alignment around architecture and long-term strategy. - I lead through influence, raise engineering standards, and stay hands-on in critical implementations. Interested in Staff / Senior Staff IC roles or Tech Lead positions within product organizations building high-impact systems.
