themes & services
Engineering services, scoped like products
Fixed deliverables, fixed timelines, senior engineers only. Here's exactly what each engagement covers.
Custom Public & Private App Development
Full-lifecycle app builds: architecture, embedded Polaris admin UI, OAuth & session management, billing, webhooks, and App Store review shepherding. We've passed review — repeatedly — and know exactly what Shopify's team checks.
- Admin REST & GraphQL API integrations
- Webhook pipelines with HMAC verification & retries
- Shopify Functions: discounts, shipping, checkout logic
- Managed Pricing & Billing API subscriptions
Custom Theme Development
From surgical Dawn customization to ground-up Liquid builds to fully headless storefronts. Every theme ships with editor-friendly sections your team can manage without us.
- Liquid themes built from scratch, OS 2.0 sections
- Dawn customization without upgrade lock-out
- Headless Shopify with Hydrogen & Storefront API
- Accessibility & conversion-focused UX baked in
Speed & Performance Optimization
We treat Core Web Vitals as a revenue lever, not a vanity score. Audit first, then a prioritized fix list executed against measured before/after benchmarks on real devices.
- Core Web Vitals boost: LCP, CLS, INP targets
- Liquid loop & render-chain cleanup
- Dead app-embed & script-tag removal
- Image/CDN pipeline & critical CSS strategy
Migration & Integration
Magento, WooCommerce or legacy carts into Shopify — catalogs, customers, order history and SEO equity intact. Plus the middleware that keeps your back office in sync afterward.
- Full-catalog migrations with URL/SEO preservation
- ERP & CRM sync middleware (NetSuite, Zoho, custom)
- Custom payment gateway & checkout integrations
- Ongoing sync pipelines with monitoring & alerting
