About Me

Hi, I'm Jay

Hi, I'm Jay

Frontend Engineer & UI Developer

Combining technical knowledge with a keen eye for design. I have roots in WordPress and email development, now specialising in building fast, scalable applications using Next.js & TypeScript. My ethos is shipping maintainable code without compromising on UX.

Frontend Development

Fast, fluid and fully responsive

I’m a big fan of the React ecosystem—specifically using Next.js, Tailwind, and modern TypeScript to turn complex designs into smooth, high-performance interfaces.

Interface Architecture

Simple, inclusive and easy to use

I pride myself on having a close eye for detail when it comes to developing UIs, also keeping user experience at the heart of every decision I make creatively.

Backend Integration

Robust and scalable

My toolkit includes Node.js & PostgreSQL (via Prisma), with experience navigating the trade-offs between SQL/NoSQL & serverless architecture.
