How I can help

01 Design & build

Complete websites and web apps, taken from brief to launch — strategy, design, development and hosting, handled end to end.

02 Product engineering

Hands-on delivery in TypeScript, React, Node.js and AWS. Mobile too — React Native apps shipped to both stores.

03 Fractional tech leadership

Architecture reviews, RFCs, team coaching and delivery process — the leadership layer, without the full-time hire.

04 SEO & growth

Technical SEO, performance and analytics, plus a pragmatic growth strategy your business can actually run.

About

Engineer first, partner throughout.

I've spent eight years building for the web — most recently as a Senior Software Engineer at AnyVan and before that as a Tech Lead at Dunelm, where I led a cross-functional team of twelve and was recognised with the 2024 Mentorship Award.

Alongside that I take on a small number of consulting projects: complete sites for independent businesses, product builds, and technical strategy. Same standards either way — measured, documented, shipped.
