I’m a senior UI software engineer with 5+ years shipping production web products using React, Next.js, and TypeScript—backed by a designer’s eye for quality and user experience. I take ownership of frontend delivery end-to-end, with a strong focus on accessibility and performance.

At a UK digital agency, I’ve owned frontend delivery for 20+ organizations, building a reusable component library/design system and shipping results that matter—page loads cut 40% and WCAG 2.2 AA audits passed. I’m comfortable working fully remote across time zones and collaborating asynchronously.

In my current principal frontend role, I’ve delivered accessible, high-performance applications for 20+ nonprofit and charity clients using React, Next.js, and TypeScript (plus WordPress/Twig builds). I rebuilt key experiences (including the UNICEF Ireland rebuild with 20+ page-builder components and 180+ Twig templates), improved donation flow outcomes, and kept mobile LCP under 2.5s while passing WCAG AA audits.

Earlier, I overhauled a high-traffic e-commerce frontend (10,000+ monthly active users), cutting page load times by 40% using code splitting, lazy loading, and image optimization. I also enjoy building reusable component libraries, mentoring developers on React patterns, accessibility, and performance, and partnering closely with product, support, and QA to reduce production issues.
