Arne is a UK multi-8-figure fashion brand ( https://www.twine.net/signin ) operating a high-volume Shopify storefront. I led Shopify Plus engineering across theme architecture, app/CMS and checkout logic, and conversion-critical PLP/PDP flows to improve release safety and commerce reliability.

I led Shopify implementation ownership across architecture, scoped delivery, QA hardening, and production readiness, with a focus on preserving revenue paths while enabling faster iteration.
Role
Lead Shopify implementation owner
Focus
Theme systems, conversion safety, integration-aware delivery
Outcome
Safer releases and stronger delivery velocity during live trading
Operating Context
Multi-8-figure live trading: theme architecture, app/CMS workflows, checkout-adjacent behaviour
Core Challenge

Deliver change safely in an integration-heavy, always-on storefront.
The environment was integration-heavy and live-trading: theme logic, app behaviour, merchandising rules, bundle logic, and checkout-adjacent flows were tightly coupled, creating high regression risk with every release. The challenge was to deliver change safely under commercial constraints while protecting variant reliability, offer logic, and conversion-path continuity across PLP, PDP, cart, and purchase journeys.

Every release had to protect browse-to-buy reliability when theme, app, and merchandising layers moved together.
Variant and offer-state behaviour had to stay predictable across collection, product, cart, and checkout-adjacent flows.
Campaign and merchandising velocity could not depend on brittle, one-off theme logic.
Work had to stay coherent across theme, app, CMS, and experimentation surfaces without trading away conversion stability.
