Shopify Custom Section Development — Liquid + JavaScript
Your Shopify theme does 80% of the job. We build the sections that do the other 20% — the conversion-driving, brand-differentiating, custom-built pieces that no free theme includes. Polished, reusable, and fully configurable from the theme editor without touching code.
Build My Shopify SectionWhat We Build
Custom Shopify 2.0 sections that drop into any theme, respect your brand, and give merchants full control via the native theme editor — no code editing required after delivery.
Testimonials & Reviews Slider
A responsive, animated testimonials carousel with star ratings, reviewer photos, and configurable layout options. Pulls from a metafield source or hardcoded blocks via the theme editor. Auto-play with pause on hover.
Before/After Image Comparison
An interactive drag-to-compare slider that showcases product transformations, room renovations, or treatment results. Touch-enabled for mobile, configurable labels, and fully responsive with no third-party dependency.
Custom Product Bundle Builder
Let customers build their own bundle — select variants, quantities, and add the whole group to cart in one click. Integrates with Shopify's cart API. Supports bundle discount logic via discount codes or automatic discounts.
Theme Settings & Schema
Every section includes a full Shopify schema with settings for colours, fonts, spacing, images, text, and toggle switches — so merchants control the section from the visual editor without opening a code file.
GitHub Delivery & Demo GIF
All sections are delivered via a private GitHub repository with clear installation instructions. A demo GIF showing the section in action is included for your portfolio, proposal, or client handoff.
Our Development Process
1. Design & Requirements Spec
We agree on layout, interactions, theme settings, and mobile behaviour before writing a line of code. Reference designs or Figma files are welcome.
2. Liquid & JavaScript Build
Write the section .liquid file with schema, the accompanying JS (vanilla, no jQuery), and any CSS scoped to the section to avoid theme conflicts.
3. Theme Integration & Testing
Install on a development theme clone. Test across Chrome, Safari, Firefox, iOS, and Android. Validate theme editor settings function correctly.
4. Performance Optimisation
Lazy-load images, defer non-critical JS, and validate that the section does not negatively impact Core Web Vitals scores.
5. GitHub Delivery & Docs
Push to a private GitHub repo with a README covering installation steps, theme settings reference, and known limitations. Record the demo GIF.

Portfolio-Ready Delivery
GitHub repo + demo GIF + documentation means your section is immediately reusable for future clients and strong enough to show in proposals.
