About

I'm a frontend-focused web developer who enjoys taking features from interface design through validation, server logic, data storage, error handling, and deployment.

I work primarily with Next.js, React, TypeScript, and Tailwind CSS. My recent work includes production client delivery, authenticated database-backed applications, server actions, external API integration, browser-side image processing, and structured AI output.

I favour clear data flow, readable TypeScript, accessible interfaces, deliberate scope, and technical decisions that are easy to explain and maintain.
