Context
Freelance technical lead, Apr–May 2026. King Double Glazing is a Melbourne retrofit double glazing business — they upgrade existing window frames with insulated glass units rather than replacing the whole window. The brief was a full rebrand from The Glass Discounters plus a new site. The actual deliverable is a conversion funnel built around one insight: show the price before asking for the phone number.

Key technical decisions
01next.js 16 › wordpress
WordPress couldn't support the Instant Estimate Tool UX without heavy plugin stacks. Next.js 16 App Router gave full control over the multi-step calculator, server actions for lead capture, and zero plugin bloat dragging down Core Web Vitals.
02price-first estimate tool › contact-first quote form
Standard trades sites gate the price behind a callback. The Instant Estimate Tool shows a price range before asking for contact details — qualify first, capture second. Filters tyre-kickers before they reach the owner's phone.
035-page conversion funnel › 27-route seo cluster
The SEO content plan was killed mid-build. The client needed leads in 30 days, not 6 months. A tight funnel pointing every visitor to the estimate tool converts faster. The SEO infrastructure (schema, sitemap, suburb template) is preserved for when the time is right.
04tinacms (git-based) › sanity cms
TinaCMS stores content as JSON files committed to the git repo — no external CDN, no separate database. Visual editor via Tina Cloud. Content is version-controlled with code. Simpler handoff for a non-technical client.
05resend + token confirmation › smtp / contact form plugin
Two-step quote confirmation: customer receives a link, clicks to confirm, then KDG gets the lead notification. Filters junk submissions before they reach the owner. DKIM/SPF/DMARC configured from day one.
Instant estimate tool — token confirmation flow
kairos/scheduler.pypy
1// server action — quote submission + token confirmation
2export async function submitQuote(data: QuoteInput) {
3 const token = crypto.randomUUID()
4 await db.insert(quotes).values({ ...data, status: 'pending', confirmToken: token })
5 await resend.emails.send({
6 to: data.email,
7 react: ,
8 })
9 // KDG only notified after customer confirms — filters junk
10}
The multi-step calculator produces a price range in under 60 seconds. On submit, the customer receives a confirmation link — KDG only gets the lead notification after they click it. Junk submissions are filtered at the email layer before they reach the owner's inbox.
