Context

The firm wanted a faster site its team could edit, without losing its visual identity or the search ranking earned by its old pages.

What I did

A pre-rendered Astro site: home, nine service lines, team, offers, workshops, a filterable searchable blog, keeping the existing identity.
Sanity for editorial content, with a fallback to local content.
Forms wired to HubSpot, protected by Turnstile, through a server route.
Migration: old articles and pages carried over at the same addresses, then a check of all 36 old URLs, titles, canonicals and structured data.
Automatic publishing: content published in Sanity builds a candidate image, verifies it, then switches Nginx over — a failing candidate leaves the live site untouched.
Docker hosting on a VPS, HTTPS certificate and a DNS cut-over that preserved email.
