How it works
From brief to production
Six stages, each with something concrete that leaves it. No phase exists to fill a slide.
- 01
Brief
Goals, catalogue, stack and constraints get written down as an agreed scope with milestones — before anyone opens an editor.
→ Scope + milestones - 02
Architecture
Information architecture, template hierarchy and URL structure are decided up front, so SEO equity and navigation survive the build.
→ IA + URL map - 03
Interface
Wireframes resolve into a design system: type scale, colour, spacing, states and the components each template actually needs.
→ Design system - 04
Engineering
Components, state, data and APIs — built in Liquid, React or both, documented so your team can own the code afterwards.
→ Production code - 05
Validation
Cross-device QA, keyboard and screen-reader passes, Core Web Vitals and analytics verification before anything ships.
→ QA + instrumentation - 06
Production
A controlled launch with monitoring in place, then iteration driven by what the funnel actually reports.
→ Live + monitored
