What I'm looking for

I'm looking to build performant, data-heavy web applications where I can own frontend architecture, collaborate closely with product and backend teams, and deliver intuitive real-time experiences.

I've built data-heavy web applications for United Airlines, CVS Health, and SAIF Corporation, turning complex operational, healthcare, and insurance data into intuitive React experiences.

At United Airlines, I built the Airport Operations Digital Twin and modernized the Disruption Management interface, improving page load times by 40% and reducing render times by 25%. I also owned frontend architecture for the United Data Hub, including a scalable component library for analytics dashboards.

I've delivered secure healthcare dashboards, patient portals, self-service insurance tools, and real-time interfaces using React, Redux, TypeScript, Node.js, REST APIs, GraphQL, WebSockets, and PostgreSQL. I care about performant UI, reliable testing, accessible design, and helping teams ship better software through strong engineering standards.
