02
Design
I map the core screens, layout, and interactions before touching code.
03
Build
I build clean, reusable components with simple state where possible.
04
Refine
I test, polish the rough edges, and ship through GitHub and Vercel.
About
I'm David, a creative front-end developer.
I'm a developer, designer and problem-solver with a background spanning enterprise systems, digital media and business technology.
My career began in business systems development, where I worked on SharePoint solutions, workflow automation and internal applications. More recently I've focused on modern web development, building applications with React, Next.js and TypeScript while continuing to expand my technical skills.
What makes my background different is the combination of development, design and business experience. I enjoy creating products that not only work well technically but are intuitive, engaging and genuinely useful for the people using them.
I'm particularly interested in SaaS products, workflow platforms, AI-powered tools and digital experiences that solve real-world problems.
