    What we actually do

    Shopify development

    Store setup and migration, custom Liquid themes, app integrations, B2B/wholesale, and conversion work. Day-to-day Shopify operator experience, not theory.

    Custom web apps

    React, Next.js, Node and TypeScript. Dashboards, internal tools, API integrations and SaaS front ends built to be maintained, not just shipped.

    Technical SEO

    Schema markup, Core Web Vitals, indexing, sitemaps and content built around real search intent — measured with real keyword data, not guesses.

    Speed & CRO

    Page speed audits and conversion optimization: faster stores rank better and sell more. We fix what actually moves revenue.

    Shopify is not a side skill here

    Our lead developer has been the sole engineer behind an international luxury fashion brand's entire Shopify ecosystem, and today runs two storefronts (B2C and B2B) for a US manufacturer across 7+ sales channels. We also operate a flagship client's store end to end — inventory, campaigns and checkout — so we make decisions like merchants, not just like developers. That is the same person who will work on your store.
