2️⃣ Conversion Rate Optimization & A/B Testing - Data-driven testing to increase RPV, CVR, and AOV backed by real user data & behavior. Not guesswork or blind best practices.

3️⃣ UX/UI Design & Audits - Figma to Shopify. Page audits. Mobile-first, conversion-focused storefronts.

4️⃣ Custom Apps, APIs & Integrations - Third-party apps, ERP integrations, checkout & account extensibility, post-purchase flows, and custom apps.

5️⃣ Migrations - WordPress, WooCommerce, Magento → Shopify. Clean and handled.

6️⃣ Accessibility & On-Page SEO - ADA compliance and foundational SEO so your store is usable and findable.

7️⃣ Ongoing Support - New features, optimization, strategic input, technical questions answered. We stay close so nothing slips.

This is a fit if:
→ You're tired of bottlenecks from slow agencies or freelancers who need constant hand-holding
→ You want Dev + UX/UI Design + CRO handled by one team and one person of contact, not scattered across vendors
→ You have a marketing team driving traffic; we'll make sure the store converts. Be as hands-on or hands-off as you'd like.
