Since 2022, I’ve been driving LegalZoom’s platform modernization efforts as a Principal Engineer, with a focus on building scalable commerce systems, enhancing developer experience, and raising the security/compliance bar across the organization. My work spans from hands-on architecture and implementation to guiding cross-functional teams through complex migrations and critical product launches.I’ve led transformations that decoupled legacy systems and enabled Salesforce-driven product launches, while also replatforming our authenticated customer experience. On the developer side, I championed CI/CD modernization and TypeScript adoption, enabling faster releases and improving productivity for 100+ engineers. On the security front, I architected org-wide CSP enforcement and spearheaded remediation of all critical vulnerabilities, directly contributing to PCI DSS v4 certification.Along the way, I’ve played a key role in stabilizing subscription/payment flows for 200K+ customers, migrating thousands of daily notifications off costly third-party vendors, and co-leading multiple high-visibility launches. Beyond delivery, I continue to shape engineering culture through design system adoption, observability improvements, and developer standards that cut onboarding time by 75%.Highlights- Modernized CI/CD, enabling daily releases and cutting pipeline times by 50%+- Reduced third-party costs by 95% via in-house notification platform- Secured PCI DSS v4 certification through proactive CSP and vulnerability remediation- Improved reliability for 200K+ active subscriptions across 15+ legacy systems- Led/Co-led 5+ major product launches, unlocking new revenue streams.
