About Me

Guy Heidemann is a full-stack web developer with years of experience building clean, responsive sites that look great and work well — Shopify and headless Shopify storefronts, WordPress builds, and React front ends. He's strongest where design meets engineering — turning mockups into reusable systems, wiring up CMS workflows non-developers can actually use, and keeping production sites fast and stable under real traffic. Under the hood he works across the stack, with Next/Node/Express services, PHP, REST and Shopify APIs, and MySQL/MongoDB data layers.
