What I'm looking for

I am seeking Shopify/eCommerce roles where I can build scalable, high-converting storefronts, lead integrations, optimize performance, and collaborate with product teams for measurable business impact.

I am a Shopify-focused software engineer with 5+ years building high-performance, conversion-driven eCommerce sites. I specialize in custom theme and app development, performance optimization, and scalable front- and back-end solutions using Shopify Liquid, modern JS frameworks, WordPress, and PHP.

I have hands-on experience with Figma-to-production workflows, third-party API integrations (REST and GraphQL), ERP/CRM integrations, testing and debugging, A/B testing, and conversion rate optimization that improved load times and conversion metrics. I deliver end-to-end solutions from feature strategy to deployment and store maintenance.

I am reliable, detail-oriented, and committed to continuous learning and client success, collaborating with cross-functional teams to produce responsive, accessible storefronts and custom Shopify apps that align technical execution with business goals.
