In both verticals, your buyers are technical, time-poor, and mobile. The legacy WordPress / Drupal / monolithic CMS stack costs you the meeting before it starts.
PILLAR 03 · PRODUCT-DEVELOPMENT RETAINER
High-Performance
Digital Engineering
Most agencies still ship slow, monolithic CMS sites with a marketing illustration on top. We sunset them. We build Astro, Node, and Python front-ends that load before the user finishes typing, PWAs that capture zero-party data on first visit, and glassmorphic UI where it earns its weight against Lighthouse scores. The site is the acquisition engine.
WHAT BREAKS IN YOUR VERTICAL
How front-end performance fails healthcare and energy buyers.
Healthcare buyers and patients live on mobile, often on legacy hardware over patchy networks. A 4-second LCP isn't a UX problem - it's an acquisition problem and an accessibility liability under WCAG 2.2 AA.
We rebuild on Astro with islands architecture, edge-cache the static surface, and keep the dynamic surfaces (patient portal, scheduling, intake) under a strict performance budget. PWAs let returning patients launch the portal without re-loading.
WE SHIP
Product-grade surfaces, not marketing illustrations.
ARTIFACT 01
Astro / Node / Python front-end
Islands architecture, server-rendered, edge-cached. Lighthouse 95+ on mobile is the floor, not the goal.
ARTIFACT 02
Progressive Web App layer
Installable, offline-capable, push-notification-ready. Captures zero-party data on first visit. Survives the user's network.
ARTIFACT 03
Glassmorphic UI + Lottie motion
Used where it earns its weight - nav, cards, modals, hero proof. Skipped everywhere else. Never at the cost of Lighthouse.
ARTIFACT 04
CMS your marketers can actually edit
CloudCannon / Sanity / Decap visual-editing wired into every content block. The marketing team ships without filing tickets.
ENGAGEMENT SHAPE
Typical six-week rebuild.
WEEKS 1–2
Architecture sprint
Audit the current stack, define the performance budget, plan the migration. Wireframes only; no design work yet.
WEEKS 3–4
Build sprint
Astro scaffold, design system, primary templates, CMS hookup, CI/CD. The marketing-editable surface goes live in staging.
WEEKS 5–6
Migration + launch
Content migration, redirects, performance pass, accessibility audit, launch. Lighthouse mobile 95+ as launch gate.
WEEK 7+
Ongoing retainer
Optional product-development retainer - feature work, A/B test instrumentation, perf monitoring. Or full handoff and we exit.
Our prior CMS scored 31 on Lighthouse mobile. Reblend rebuilt the front-end on Astro in six weeks and we launched at 97. Mobile organic sessions are 2.4x what they were last quarter.
A fast front-end is only useful if you can measure what it's catching.
Most engineering engagements lead into the other two pillars - Predictive Pipeline instruments what the front-end captures, Bespoke AI Workflows turn the captured data into operator-callable workflows.
Scope an Engineering sprint.
Typical first sprint - two weeks, fixed fee, ends with a performance audit and a migration plan. You own the audit and the wireframes regardless of next steps.
