Skills & technology
No page builders, no themes, no lock-in. Every Coselli site is a hand-built software project — and every skill below is running in production on a client site right now. Click any example to see it live.
01
Every Coselli site is a real software build, not a page-builder theme. The stack is chosen for speed, type safety and long-term maintainability.
Component-driven interfaces with end-to-end type safety. The same architecture runs marketing sites, multi-venue group sites and data-heavy platforms.

Framer Motion for scroll reveals, kinetic type and interface feedback — always gated behind reduced-motion preferences and never in the way of the content.

When a site needs to do more than present — take enquiries, hold catalogues, run workflows — we build the backend to match.
Structured data models with row-level security behind catalogues, valuation tools and intake systems. Data stays yours, portable and queryable.

Visibility is engineered in from the first commit, not bolted on later. Every build is optimised for both classic search engines and AI answer engines.
Schema.org markup for organisations, services, products and creative work so Google and AI assistants understand exactly what a business does and where.

Technology carries the design — it never leads it. These are the disciplines behind how the work looks and feels.
Broken grids, generous whitespace and print-inspired composition that make a site read like a well-made magazine rather than a template.
