I build the small systems a business actually runs on.

All six are running live below — the real pages, not screenshots. Press Try it on any frame to use it right here: rotate the bottle, change the fragrance, scroll the lens apart. Open takes you to the full site.

Apps Script invoicing with a guard that stops a re-run sending twice. The script is printed on the page.

Redhill Ops
Redhill Ops Open

An operations view off a Google Sheet. Every chart hand-drawn SVG — no charting library.

Northbridge Dental
Northbridge Dental Open

One page, one job: getting an anxious person to book. No invented testimonials, no countdown.

Meridian 50mm
Meridian 50mm Open

Scroll and the lens comes apart, then reassembles. Every part is geometry written in code.

Auréole
Auréole Open

Pick a fragrance and the liquid changes colour behind real refracting glass. Nothing loaded from a model file.

HÜMA
HÜMA Open

Four flavours under a drawn dome. Every mark is SVG and CSS — no image files at all.

A note on all six

They are demos, not client projects. I built them to be opened and picked apart, because a screenshot of work sitting behind an NDA tells you nothing about whether the person can actually build. The brands are invented; the code is real.

If you are weighing me against someone with a long review history, that is a fair thing to weigh. What I can offer instead is work you can run before you hire me.
