What I'm looking for

I’m looking to join a team where I can own Shopify/Shopify Plus builds end-to-end, develop custom apps, and improve performance and conversion. I want clear communication, fast execution, and measurable results in e-commerce.

I’m a Senior Shopify Developer & E-commerce Specialist, focused on building fast, clean, conversion-ready stores that are built to move the needle. I work across the full Shopify stack—from custom theme and app development to performance and user experience.

I’ve developed custom Shopify apps to add functionality beyond what Shopify offers natively, translating complex client needs into maintainable, decision-ready solutions. I’m also comfortable owning end-to-end builds, from discovery through launch and post-launch support.

In my recent roles, I delivered high-impact Shopify and Shopify Plus projects for US and Canadian brands, managing multiple workstreams while staying clear with stakeholders across time zones. I’ve also supported CRO initiatives and integrated payments, CRMs, and marketing tools to ensure everything works together seamlessly.
