What I'm looking for

I enjoy working directly with US and international design, marketing, and product teams—understanding what they want to achieve and finding the cleanest, most reliable way to build it.

I build Shopify and Shopify Plus stores from Figma designs and creative briefs, including mobile-first landing pages and reusable theme sections. In my current freelance consultancy work, I customize carts, checkout flows, payment gateways, and marketing integrations.

For Old School Brand & Springbok Retail, I rebuilt the product size selection flow, helping increase average order value by 22% while keeping page loads under two seconds. I also redesigned product cards, driving around 18% more add-to-carts before the update was rolled out across the business.

On the Drive Medical initiative, I led frontend development across discovery, scoping, and launch. I supported migrations from WooCommerce to Shopify and built HubSpot CMS pages and brand layouts that worked alongside SAP e-commerce.

Earlier, at Bitcube, I improved a client's storefront speed by roughly 33% by replacing older jQuery with TypeScript and reusable Web Components. I also review and test AI-generated code as a freelance AI Code Evaluator & Prompt Specialist.
