Build · Engineering
Shopify engineering that survives the platform's roadmap.
Themes, headless storefronts, checkout, apps, and migrations — built by engineers who work in Liquid, Hydrogen, and the Admin API every day. Everything upgrade-safe, everything documented, everything your team can inherit.
Store builds & custom themes
A Shopify build is an architecture decision disguised as a design project. Get the theme structure wrong and every future campaign, translation, and A/B test costs triple. We build on Online Store 2.0 primitives — JSON templates, section groups, metafields, and metaobjects — so merchandisers can restructure pages without engineering tickets.
What a build includes
- Figma-to-theme translation — your design file built pixel-faithful into OS 2.0, or full creative direction from our design team if you're starting without one
- Information architecture mapped from your catalog and search demand, not a template's defaults
- Design system tokens in the theme: spacing, type, and color as settings, not hardcoded CSS
- Metafield/metaobject content model so PDPs scale past the standard description field
- Performance budget enforced from the first commit — 90+ Lighthouse is the floor, not the goal
- Documentation and a recorded walkthrough so your team owns the theme on day one
We're equally comfortable hardening an existing theme: refactoring app-script bloat, removing dead snippets, and getting a store that's accumulated three agencies' worth of patches back to a maintainable baseline.
Headless & Hydrogen
Hydrogen — Shopify's React framework on Oxygen hosting — is the right call when your storefront needs app-grade interactivity, heavy content orchestration, or sub-second navigation at serious scale. It's the wrong call surprisingly often, and the difference is carrying cost: a headless stack means a JavaScript codebase your team maintains forever.
Our rule: headless has to earn its keep against a well-built Liquid theme, which hits the same Core Web Vitals for most brands. When it does earn it, we ship Hydrogen storefronts with server-side rendering, Storefront API caching strategy, and a content pipeline from your CMS — and we benchmark against the Liquid baseline so the decision stays honest.
Checkout extensibility & Shopify Functions
Checkout is where customization used to go to die — script tags and checkout.liquid hacks that broke on every platform update. The extensibility era fixed that, and it's where we do some of our most valuable work.
- Checkout UI extensions — trust badges, delivery pickers, upsells, and custom fields rendered natively inside checkout, upgrade-safe by design
- Discount Functions — stacking logic, tiered volume pricing, and member pricing that Shopify's native discounts can't express
- Delivery & payment Functions — rules that show the right shipping and payment options per cart, per market, per customer segment
- Post-purchase extensions — one-click offers in the highest-converting real estate you own
Every Function ships with test coverage and a plain-English spec of the business rule it encodes, so the logic outlives the engineer who wrote it.
Apps, integrations & systems
Most integration problems are reconciliation problems: two systems that disagree about inventory, orders, or customers. We build private apps on the Admin API with webhook-driven sync and explicit reconciliation reports, so when systems drift, you know the same day — not at month-end close.
- ERP and accounting sync (orders, inventory, and fulfillment state, both directions)
- 3PL and WMS integrations with exception queues instead of silent failures
- CRM and support-desk pipelines with full order context attached
- Custom admin tooling — bulk operations, merchandising dashboards, internal approval flows
Migrations & replatforming
Replatforming is a controlled inventory move: every URL, product, customer, order, subscription, and rank position is either carried over or written off deliberately. From Magento, WooCommerce, BigCommerce, Salesforce Commerce Cloud, or custom carts, the process is the same discipline:
- Full crawl and analytics baseline before anything moves — traffic is counted like stock
- URL-by-URL redirect map, including parameterized and paginated URLs everyone forgets
- Data migration with checksums: products, customers with password strategy, order history, gift cards, subscription state
- Structured-data and meta parity so rich results don't blink out at cutover
- Parallel-run validation window and written rollback criteria before DNS changes
The result we're accountable for isn't "the new site is live" — it's organic revenue intact 90 days after cutover.
Common questions
Engineering, answered plainly.
Do you build custom themes or customize existing ones?
Both, honestly scoped. If a Dawn-based build gets you to market faster with the same conversion outcome, we say so. Ground-up themes are for brands whose design system or performance targets genuinely exceed theme customization. Either way you get OS 2.0 architecture your team can edit without a developer.
When does headless make sense?
When you need app-grade interactivity, complex CMS orchestration, or sub-second navigation at scale — and can carry a React codebase long-term. Under that bar, a well-built Liquid theme hits the same Core Web Vitals cheaper. We recommend against headless more often than for it.
Can you migrate us without losing rankings?
Migrations run behind URL-by-URL redirect maps, structured-data parity checks, and before/after crawl comparison, with rollback criteria agreed before DNS moves. Organic traffic is treated as inventory — counted before, verified after.
Who owns the code?
You do — full stop. Everything lives in your repo (or one we hand over), with documentation and recorded walkthroughs. No agency lock-in, no black boxes.
