Why work with me

Most freelancers can build you a website. Fewer have shipped software that millions of people use. I've spent my career as a senior engineer inside companies like Dunelm, CRU Group and Certinia — building the systems, pipelines and interfaces that big businesses depend on.

Now I bring that same engineering standard to businesses that can't afford to get their website wrong. When you work with me, there's no junior doing the real work and no agency markup — just one experienced engineer who owns your result from first call to launchhhhh.
