Available to hire
I’m a Full Stack Web Developer with over seven years of experience specializing in Shopify and front-end development. I focus on building high-quality Shopify stores, custom themes, and headless Shopify solutions, as well as developing custom Shopify apps tailored to complex business needs.
I have extensive experience integrating third-party ecommerce tools such as Recharge, Rebuy, Klaviyo, and Yotpo into seamless customer flows. My technical background includes deep hands-on work with the Shopify APIs (GraphQL and REST), webhooks, and scalable front-end architectures that prioritize performance and conversion.
Beyond development, I place a strong emphasis on code quality, maintainability, and collaboration. I write clean, well-documented code, automate testing and CI/CD pipelines, and actively mentor junior developers on best practices. Comfortable working across the full stack, I consistently translate business goals into robust, scalable storefronts that help brands grow while delivering reliable performance.
