What I'm looking for

I’m looking to build and modernize high-traffic web products with strong accessibility (WCAG), performance, and scalable engineering. I want ownership of complex frontend and platform work, plus opportunities to mentor teams and ship reliable features globally.

I’m a Senior Software Engineer with 11 years of experience designing and maintaining large-scale enterprise applications.

I specialize in migrating legacy systems to modern standards while delivering measurable performance improvements.

In my current role, I lead a high-traffic ecosystem with 10M+ visitors and 21M+ views, using TypeScript to drive a 90% annual increase in traffic. I also built localization and redirection logic for the US, JP, UK, and AU markets to ensure efficient global delivery.

I’ve engineered interactive, modular systems with Angular, Node.js, and Contentful, including an AI-assisted wrap component narrative experience. I focus on WCAG accessibility and mentoring, turning complex requirements into scalable frontends.

Previously, I built high-performance landing pages for Google’s Small Business initiatives, using React and Next.js. I ensured WCAG compliance and peak performance in high-traffic systems using TypeScript, GraphQL, and RxJS, delivering responsive, reliable results.

Happy to help you with anything you need!
