Liquid & themes
Existing themes are extended selectively or built as custom components, without creating unnecessary dependencies.
NJUME Studio · Berlin
Shopify Developer Berlin.
When a ready-made theme or a standard app isn't enough, NJUME builds custom Shopify features — from Liquid and custom sections to apps, APIs, and data flows.
Sections & product logic
Flexible content areas, metafields, variant logic, bundles, and special product presentations are built to suit the range.
Shopify apps
Custom apps and server-side functions are used where theme code or standard apps can't cover the requirement reliably.
APIs & webhooks
Shopify can be connected to CRM, ERP, inventory systems, Klaviyo, support, and custom systems.
Automation
Orders, products, stock levels, and customer data can be passed on in a controlled way. For complex workflows we connect n8n and AI automation where needed.
Testing & operations
Error cases, limits, permissions, privacy, performance, and later maintenance are taken into account before going live.
A custom feature instead of an app collection.
Requirement
Clarify business logic, data, and the desired behavior.
Architecture
Deliberately choose theme, app, API, or automation.
Development
Build the feature and test it with realistic data.
Handover
Publish, document, and keep supporting.
Adapt the theme or build a new one?
That depends on the quality, scope, and desired flexibility of the existing theme. We first check what's solid.
Standard app or custom feature?
A good standard app is often more economical. Custom development pays off for special logic, data ownership, or limits that keep getting in the way.
Headless Shopify too?
Yes, if content, frontend, and operations justify the additional architectural effort. Headless isn't an end in itself.
Only Shopify?
No. For hand-coded websites, portals, Vercel, and general APIs, see our custom web development.
