[01] Competence

Three things our platform actually solves for e-com.

Specialised in Shopify, fluent in everything else. We build infrastructure for stores that have outgrown templates — integrations, custom apps, automation.
/01 — Shopify Admin API

Deep integration with the Shopify Admin API.

GraphQL & REST, bulk operations, webhooks, custom apps, checkout extensions. We treat the API as a contract, not a workaround.

POST/admin/api/graphql.json · bulkOperationRunQueryqueue
PATCH/admin/api/2025-01/inventory_levels.json62ms
POST/admin/api/2025-01/webhooks.json47ms
/02 — High-load ready

Handles real e-com volume.

100k+ SKU catalogs, peak-traffic launches, BFCM-grade events — without dropping orders.

/03 — Security & stability

Zero-config secrets · Root-access governance.

Scoped tokens, audited deploys, per-store role separation, GDPR-aware data flow.

/04 — Stack fluency

Beyond Shopify, where it matters.

We meet your stack where it lives — ERP, PIM, ESP, headless. No re-platform required.

Cartly: e-commerce without the compromises.

Beyond Shopify Plus and headless stacks, we built our own cloud e-commerce platform. Liquid + sections from OS 2.0, headless flexibility from React Islands, and a unified GraphQL API — on the same engineering stack we use across every brand we ship.
