The problem
Why standard web development breaks Shopify stores
Most development agencies build pretty websites, but they don’t understand the rigorous demands of modern ecommerce. When you hire generalists to build on Shopify, you run into the same revenue-killing problems:
Bloated, slow themes
Over-reliance on heavy apps and sloppy Liquid code destroys your Core Web Vitals and mobile conversion rates.
Broken integrations
Critical ERP, 3PL, or marketing tools fail to sync correctly, causing fulfillment nightmares.
Terrifying deployments
Pushing code to a live store without rigorous Quality Assurance (QA), leading to broken checkouts during peak traffic.
Zero post-launch support
The agency disappears after launch, leaving you without a technical partner to scale.
We are dedicated Shopify specialists. We engineer stores for maximum speed, seamless back-office integration, and zero-downtime deployments.
Everything a Shopify build needs.

Built for merchants
The features you want, none of the hassle.
Your team runs the store day to day. We make sure nothing about the build gets in their way.
What we build
Specialized Shopify & Shopify Plus capabilities
Custom theme & store builds
We build bespoke, high-converting Shopify storefronts from scratch. We write clean, modular Liquid code that perfectly matches your brand guidelines while keeping the DOM light for blazing-fast load speeds.
Headless commerce & Hydrogen
For enterprise brands requiring ultimate flexibility, we decouple the front-end using Shopify Hydrogen and React. This delivers sub-second page transitions, limitless customization, and omnichannel capabilities.
Custom app & integration development
Stop relying on duct-tape solutions. We build private Shopify apps to connect your store directly with bespoke ERPs, complex PIM systems, or custom fulfillment center APIs.
Platform migrations to Shopify
We handle complex data migrations from Magento, WooCommerce, or BigCommerce. We safely port your customer data, order history, and SEO link equity with zero data loss and minimal downtime.
Checkout Extensibility (Shopify Plus)
We maximize your Average Order Value (AOV) by customizing the Shopify Plus checkout experience. We implement advanced post-purchase upsells, custom loyalty point redemptions, and unique B2B wholesale rules.

PPauline MercierE-commerce Director, HearthlineThe answers to your questions.
Yes, we are highly experienced in Shopify Plus development. We regularly implement Plus-exclusive features like Checkout Extensibility, B2B on Shopify, custom Launchpad scripts, and advanced API rate limit management for enterprise merchants.
A standard custom Shopify theme build typically takes between 6 to 10 weeks from discovery to launch. Complex headless builds (using Hydrogen) or massive data migrations from legacy platforms like Magento can take 12 to 16 weeks depending on data complexity.
Yes, page speed optimization is a core part of our development philosophy. We achieve sub-second load times by refactoring heavy Liquid code, deferring non-critical JavaScript, compressing assets, and eliminating bloated third-party apps.
A poorly handled migration will hurt SEO, but our technical migration process prevents traffic drops. We map and implement 1-to-1 301 redirects for every URL, migrate all meta data, and match your existing site architecture to protect your search rankings.
Yes, we offer flexible, ongoing retainer agreements for post-launch support. We act as your fractional engineering team to continuously deploy conversion rate optimization (CRO) updates, update apps, and build new seasonal features.
