Shopify development
Shopify handles the hard parts of selling (checkout, payments, fraud, scale) so the build can focus on what converts. We engineer Shopify themes, Hydrogen storefronts and custom apps for serious merchants.
In short
Shopify, at a glance
- Shop Pay and a relentlessly optimised checkout lift conversion out of the box.
- Shopify absorbs traffic spikes that break self-hosted carts, so peak day is just a day.
- Hydrogen and the Storefront API give full frontend control with platform reliability.
- Thousands of integrations, plus custom apps where they fall short.
Why Shopify
Shopify in production.
Shopify's checkout is among the highest-converting in commerce, and its infrastructure absorbs flash-sale traffic that would flatten custom carts. The platform question isn't whether it scales. It's how well your build uses it.
We work across the whole surface: conversion-tuned themes on Online Store 2.0, headless Hydrogen storefronts when the brand demands full control, and custom apps that bend the platform to your operations.

Shopify questions, answered.
Still unsure if Shopify is right for your project? A senior engineer will tell you straight on a free call.
For most merchants, Shopify: checkout conversion, PCI and peak-day scale are solved problems. Custom builds make sense only for genuinely unusual commerce models, and we'll tell you honestly which you have.
When brand experience, content richness or performance ambitions outgrow theme constraints, and you have the appetite for a frontend codebase. Otherwise, a well-built OS 2.0 theme delivers superb results for less.
Yes. Full catalog, customer and order history migration with SEO-preserving redirects and a rehearsed cutover. Rankings and revenue carry over; the legacy maintenance burden doesn't.
Both private apps for your own operations and public apps for the App Store: admin extensions, Shopify Functions for checkout logic, and webhook-driven integrations with your back office.
Shopify's platform will, and we make sure your build does too: load-tested themes, optimised apps and a performance budget that keeps the storefront fast under fire.
