E-Commerce Development
Storefronts that convert and checkouts that don't break at scale.
We build e-commerce storefronts for founders — headless Shopify Hydrogen when you need custom UX, a hardened Shopify Plus theme when speed matters more, custom carts when the platform gets in the way. One senior engineer owns checkout, inventory sync, and the storefront, so launch day isn't held together by three unrelated apps.
What you get
Concrete deliverables.
Not a slide deck.
- Storefront live — headless Hydrogen build or a hardened Shopify Plus theme, whichever fits your timeline and design ambition
- Checkout wired correctly: discounts, bundles, subscriptions via Shopify's native checkout, no third-party checkout hacks that break at scale
- Inventory and order sync with your fulfillment provider or 3PL — no manual CSV exports
- Email/SMS flows wired (Klaviyo or Postscript) for abandoned cart, post-purchase, win-back
- Performance budget held — Core Web Vitals green on the product and collection pages that actually drive conversion
Why us
The shape of the work matters.
- Senior engineer who has shipped headless Hydrogen builds, not just installed theme apps
- We know where Shopify's app ecosystem is worth using and where it becomes technical debt
- Checkout and inventory correctness treated like fintech-grade problems — a broken checkout is lost revenue, not a bug ticket
- Flat price includes the launch-week firefighting most agencies bill as a change order

FAQ
Questions founders ask.
How fast can you start?
Most builds begin within seven days of the first call. We don't sell discovery — we go from problem statement to first deploy on the same day-one timeline.
Is the price really flat?
Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.
Headless Hydrogen or a Shopify Plus theme?
Theme-based if you need to launch in two weeks and the design is close to what Shopify templates support well. Headless Hydrogen if you need custom UX, sub-second page loads, or you're integrating commerce into a larger product rather than shipping a standalone storefront.
Do you migrate from another platform?
Yes — most commonly from WooCommerce or a custom cart to Shopify. Product catalog, customer accounts, and order history migrate; we flag anything that won't map cleanly before we start.
Who owns the code?
You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
