Sales-Driven Landing Page Build

I need a developer who can transform my sales strategy into a set of high-converting landing pages. The priority is clear: every design choice must help me boost sales. The project falls squarely under développement web, yet it must respect the principles of performance-oriented marketing numérique.

Here is how I picture the workflow:
• Strategy & wireframes – translate my offer into persuasive page layouts that guide visitors toward a single call-to-action.
• Pixel-perfect build – responsive HTML/CSS/JS (or WordPress/Shopify if a CMS accelerates deployment), fast loading, SEO-friendly, fully mobile-ready.
• Conversion plumbing – embed analytics, event tracking, and A/B-test hooks so I can measure and iterate.
• Final QA & launch – pages go live bug-free, with clear hand-off notes so I can update copy or images without touching code.

Acceptance criteria:
1. Landing pages load in under 3 s on 4G according to PageSpeed Insights.
2. All key actions (form submit, button clicks) fire conversion events in Google Analytics 4.
3. Pages render flawlessly on the latest versions of Chrome, Safari, Firefox, and Edge, desktop and mobile.

If this matches your expertise, let’s talk timing and any assets you’ll need from me.
