About

I am an accomplished Senior Front-End Engineer and UI/UX Architect with over 10 years of experience designing, developing, and deploying enterprise-grade SPAs. I specialize in digital accessibility (AODA, WCAG 2.2 AA, WAI-ARIA) and secure web architecture, delivering human-centric, compliant digital solutions. I have hands-on expertise with modern JavaScript frameworks like React and Backbone.js, robust REST API integrations, and secure authentication flows (OIDC, PKCE, OAuth 2.0).

I provide technical leadership, guide multi-tier testing lifecycles, and collaborate with cross-functional stakeholders to deliver seamless public and enterprise platforms. My work emphasizes inclusive design, keyboard navigability, and scalable architecture that withstands regulatory scrutiny and evolving security requirements.
