Four ways I help
merchants win.
Pick a lane — or describe your project and I'll tell you honestly if it's a fit.
Shopify Theme Development
Custom Liquid themes from Figma to pixel-perfect production. Dawn-based or fully from scratch — sections, metafields, localization, and everything in between.
Custom Shopify Apps
Embedded admin apps, public App Store apps, Shopify Functions, metafields, and webhooks. React + Polaris + GraphQL Admin API — built to pass Shopify review.
CRO & AOV Optimization
Turn more visitors into buyers and increase average order value. Upsells, cross-sells, urgency elements, smart cart design, A/B testing — data-driven decisions that move revenue.
Performance & Headless
Lighthouse 90+, Core Web Vitals green, LCP under 2.5s. Also headless storefronts with Shopify Storefront API + Hydrogen for brands that need full custom UX.
