ENGINEERING VALUES

Development Principles

Clean Code
Every line of Liquid, JavaScript, and CSS has a clear purpose. We write modular, well-structured code engineered for long-term maintainability.
Strict BEM CSS naming, clean Git history, zero technical debt, and isolated section components.
Shopify First
We leverage native OS 2.0 architecture, Metaobjects, and Shopify Flow automations instead of relying on heavy third-party page builders.
Native Liquid templating, custom bundle decomposition, zero app bloat, and full customization.
Mobile Focused
Over 70% of e-commerce traffic is mobile. We design and build touch-first interfaces, smooth gestures, and responsive layouts from day one.
Fluid clamp typography, optimized touch targets, fast AJAX drawers, and adaptive media loading.
Performance Driven
Speed directly drives conversion. We optimize Core Web Vitals, minimize layout shifts (CLS), and streamline storefront asset loading.
Native Web Components, sub-second response times, LCP preloading, and clean DOM structures.
HOW WE WORK

The Process

01

Discovery

1 – 2 Days

We dive into your existing theme codebase, analyze current app integrations, review performance metrics, and clarify all technical requirements. We ensure we understand every business goal before writing a single line of code.

KEY DELIVERABLES
  • Comprehensive theme code & speed audit
  • App stack & integration review
  • Project scope & technical specification

Planning

2 – 3 Days

We design the Liquid theme structure, map custom metaobjects and schema settings, and plan data workflows for apps like Shopify Flow. Everything is structured so your team can easily manage content from the Shopify admin later.

KEY DELIVERABLES
  • OS 2.0 section & schema architecture
  • Metafield & Metaobject structure mapping
  • Shopify Flow automation flowchart

3 – 10 Days

Development happens in a separate unpublished theme duplicate or development store using Git. We engineer clean Liquid templates, Web Components, custom JS/CSS, and configure app integrations with zero impact on your live store.

KEY DELIVERABLES
  • Modular Liquid & BEM CSS development
  • Custom AJAX drawers, swatches & calculators
  • Shopify Flow & app integrations
