Hi, I'm Sef.

I've been building for the web for ten years. My day job is senior front-end developer at a MarTech SaaS company, working on products used by large global brands — so most of my week is spent on complex platforms where the details genuinely matter and nothing ships half-finished.

That work is mostly TypeScript, React and Next.js: making things fast, accessible, and solid enough to hold up under real use by a lot of people. Along the way I've picked up the less glamorous half of the job too — code review, mentoring, architecture decisions, and the CI/CD plumbing that keeps releases boring. More recently that has included shipping a production Model Context Protocol server, so an AI assistant can query a live dataset of 169,000+ records directly rather than through a chat box bolted onto a website.

Evenings and weekends, I do this. Websites and small applications for small businesses, which is a deliberate change of scale rather than a step down. You get the same standards I'd apply to a product with thousands of users, on a four-page site for a business round the corner — and you talk to the person actually building it, not an account manager passing messages along.

If you're weighing up whether to get in touch: there's no hard sell at this end. A first chat is free and genuinely no-obligation, and if I'm not the right fit for what you need, I'll tell you straight away rather than talk you into something.
