Portfolio · Development

Builds that stay fast under load.

The engineering behind the sites we ship, booking engines, payments, ecommerce and intake flows, all built to a performance budget rather than a performance promise.

Centered Spa · centeredspa.com

Booking engine + service catalogue

Service and membership data modelled once, then reused across menus, add-ons and the booking widget. Deep links drop guests straight into the right service with the right duration pre-selected.

Two-tap booking path; zero manual menu updates.

The Shot Labs · theshotlabs.com

Multi-location scheduling & intake

Location-aware scheduling wired to consent and intake forms, with conditional questions per treatment and secure hand-off to the clinic's records system.

Paperwork completed before arrival on most visits.

NexGeneration Jewelry · nexgenerationjewelry.com

Ecommerce build & checkout tuning

Variant-heavy product catalogue, image pipeline with responsive AVIF/WebP output, cart persistence and a trimmed checkout with express payment options.

Faster product pages; fewer abandoned carts.

Crimson Dove Tattoo · crimsondovetattoo.com

Portfolio CMS & consultation flow

Artist-managed portfolio uploads with automatic image optimisation and style tagging, feeding a consultation request form that routes to the right artist.

Same-day portfolio updates without developer time.

Manifest For Me · manifestforme.com

Content platform & member access

Structured content library with gated resources, email capture and payment-backed access, built to publish new material without touching code.

Self-serve publishing for the whole library.

Real Psychiatry Now · realpsychiatrynow.com

Telepsychiatry intake & privacy hardening

Encrypted intake forms, insurance eligibility questions, appointment routing and strict third-party script control to keep patient data contained.

Clean, privacy-conscious intake from first click.

FAQ

Questions, answered

More questions
What technologies do you build with?+

Modern, widely supported stacks chosen for longevity: React-based front ends, performant hosting and a CMS matched to how your team likes to work.

Can you take over a site another developer built?+

Usually, yes. We start with a code and hosting audit, stabilise what exists, then improve it in stages rather than forcing an unnecessary rebuild.

Do you provide hosting and maintenance?+

Yes. We manage hosting, updates, backups and security monitoring as part of our care plans, with everything documented and owned by you.
