Recent Work
2021 - 2025
HMRC Customs Search Service (via Equal Experts)
Building a React, Next.js search application
For three years I lead the frontend development of the new HMRC Customs Search Service: a multipage React, Next.js application that served ~400 million records to an internal team of ~2000. It allowed staff to use various filters & search criteria to find specific records. Further details of this project can be found on my C.V.
2018 - 2021
Sky Betting & Gaming
Building multiple apps for millions of users
I helped develop the fastest (at the time) login interface in the betting industry. Comprised of a SSR login interface using React, Redux & Next.js. I also rebuilt multiple safer gambling applications, migrating them from older technologies like create-react-app, class components and redux, to Next.js, TypeScript and hooks.
Additionally myself and another engineer developed a boilerplate application island, using Yarn Workspaces and Next.js, to solve tribe-wide scaling and performance issues. Further details of this project can be found on my C.V.



2016 - 2018
UAccount
Creating a new front end from the ground up, and introducing React
I led the front-end development in building a new, scalable and robust front-end architecture, combined with a living component library. This allowed developers to be more effective, but more importantly led to a better UX for users.
I also built the foundations of an entirely new React based front end, introduced front end guidelines covering everything from principles to code structure, carried out performance audits, trained other members of staff to improve their front-end skills and understanding of scalable design systems.


2016
World Wildlife Fund
Building a new front-end system for one of the worlds largest charities.
I had the pleasure of leading the front-end development for one of the worlds largest charities. I created a flexible, component based front-end system, coding guidelines and a living styleguide to make future updates and site maintenance as easy as possible.
This made it easy to create unique page layouts by choosing from a selection of components. This helped developers working on the site as well as leading to a more consistent user experience for site visitors.



Projects
2024
The Random Show
The Random Show is a great podcast, but the episodes can be hard to track down as they're hosted in various places, on different domains. So I made this little site to bring them all together.
2022
Episode Ratings acquired
See if a TV show improves or declines over time. Features include episode rating graph, "Where to watch" based on your location, best & worst episodes, episode summaries, and similar shows.
A fullstack application built with React, Next.js, Zustand, EmotionCSS, Tailwind, serverless (Next.js API routes), multiple APIs, and MongoDB. Pages are statically generated at build time and incrementally regenerated for performance.
