Wix web development USA

Wix templates run out of room fast. The booking flow doesn't fit your business. The CRM won't sync. Page speed tanks. Our Wix developers code custom Velo, real integrations, and performance-tuned features so your site keeps up with your growth.

01

When drag-and-drop stops being enough

You'll feel it the moment your business outgrows the template: LCP creeps past 4 seconds, your booking page can't handle conditional logic, the CRM integration breaks every Tuesday, and your member area is a Frankenstein of free apps.

That's where a real Wix expert for service businesses takes over. We rebuild critical flows in Velo — Wix's native JavaScript runtime — so your site does exactly what your operation needs, instead of the other way around.

02

Custom Velo code & Wix integrations

We ship custom Wix integrations every week. Most clients ask for some combination of the stack below — but if it has an API, we can wire it.

  • 01Stripe, Square and PayPal — custom checkout, subscriptions, donations.
  • 02HubSpot, Salesforce, Pipedrive — two-way CRM sync from any Wix form.
  • 03Calendly, Acuity, native Wix Bookings — conditional logic, multi-resource scheduling.
  • 04Mailchimp, Klaviyo, ConvertKit — segmented signup flows from Velo.
  • 05Make (Integromat), Zapier, n8n — orchestrate everything else.
  • 06Airtable, Google Sheets, Notion — dynamic content surfaced as Wix collections.
  • 07Custom REST APIs — we'll build the backend if you don't have one.
03

Wix site speed optimization, included

Performance is part of every Wix web development USA engagement. We convert images to WebP/AVIF, code-split with Velo, defer third-party scripts, lazy-load below the fold, and pre-render dynamic Wix Studio pages where it matters.

Target: sub-2.5s LCP, CLS under 0.1, INP under 200ms, and a 90+ Lighthouse mobile score. We measure it before launch, after launch, and every month forever.

— 002 / How we engineer your site

Four pillars. One reliable build.

Most Wix sites are stitched together by a non-coder and held up with hope. Ours are engineered like the products they are.

01

Custom Velo Development

We use Wix's Velo platform to write real JavaScript where drag-and-drop falls short — booking flows, member areas, dynamic catalogs, multi-step forms, and complex business logic written, tested, and shipped by senior engineers.

  • Custom JavaScript & TypeScript
  • Modular, documented Velo code
  • Backend functions with auth
  • Reusable components per project
02

Real API Integrations

Stripe, HubSpot, Salesforce, Calendly, Twilio, Mailchimp, Airtable, Google Workspace, custom REST APIs — we wire your Wix site into the tools you already run, with proper auth, error handling and retries.

  • Stripe, CRMs, calendars, SMS
  • Webhooks & real-time syncs
  • Secure API key management
  • Error logging & retries
03

Performance Engineering

Sloppy code kills rankings and conversions. We lazy-load scripts, debounce expensive calls, optimize images, and benchmark every feature against Core Web Vitals so your site stays fast as it grows.

  • Core Web Vitals 90+ on mobile
  • Lazy-loaded media & scripts
  • Image & font optimization
  • Caching & CDN tuning
04

Quality, Security & Handover

Every line is code-reviewed, version-controlled in Git, and documented. Secrets stay in env vars, forms have validation and rate-limiting, and you get a clean handover doc — so any developer can pick it up later.

  • Git version control
  • Code review on every PR
  • Form validation & rate-limits
  • Documented handover guide

— Real builds, shipped

Custom features that earn their keep.

Three real Wix sites. Three custom builds. None of them possible with drag-and-drop alone.

— Why engineered wins

The unfair advantage of a site that scales.

Anyone can drag four sections onto a Wix template. The moment you need a real booking flow, a Stripe integration, a member area, or a 96 PageSpeed score — you need an engineer. We're the engineer your competitors don't have.

Speed that ranks and converts

Properly engineered code keeps Core Web Vitals green — Google rewards it, customers feel it.

Real backends, not workarounds

Bookings, subscriptions, member areas and dashboards built like products, not duct tape.

Maintainable forever

Modular, documented, version-controlled code. Any developer can pick it up — you're never stuck.

Secure & compliant

Validated forms, rate limits, env-var secrets, GDPR-friendly defaults. Your data stays your data.
