⚡ 8+ years designing and developing WordPress, Shopify & Webflow websites ⚡ 300+ sites shipped across WordPress, Shopify, and Webflow prior to joining Upwork I build fast, conversion-focused websites and online stores using Shopify, WordPress, and Webflow for businesses that need a site that actually converts, not just looks good. WHAT I DO: - Shopify store builds, theme customization, and store migrations - Custom WordPress & WooCommerce websites - Webflow design and development (Figma to Webflow) - Website redesigns and landing pages built for conversion - Speed, SEO, and mobile optimization on every build MY PROCESS: Figma design → development → mobile optimization → testing → launch. You get clear communication, an organized build, and a site you can actually manage after I hand it off. RECENT RESULTS: - Rebuilt a Shopify store's checkout flow — reduced page load time by 40% - Migrated a legacy WordPress site to WooCommerce with zero downtime - Webflow redesign for a service business — increased mobile conversions WHY WORK WITH ME: ✔ Shopify Certified Partner & Webflow Visual Developer Certified ✔ 10+ years in web design/development ✔ Strong Figma/UI/UX foundation on every project ✔ SEO-friendly, performance-first builds ✔ Comfortable improving existing sites or building from scratch Q: Do you work with existing websites or only new builds? A: Both. I regularly redesign and improve existing WordPress, Shopify, and Webflow sites. Q: Can you convert my Figma design into Webflow or Shopify? A: Yes — Figma to Webflow and Figma to Shopify conversions are a core part of my process. Q: How fast can you turn around a project? A: Landing pages typically take 3–5 days; full store or site builds run 1–3 weeks depending on scope. Q: Do you offer post-launch support? A: Yes, I offer ongoing maintenance and support after launch. I also have a full-stack JavaScript background (React, Next.js, Node.js) for projects that need custom functionality beyond what a CMS or theme can handle. - I am responsive, professional and communicates clearly Send me your project details and I'll tell you the fastest path to launch.
