A closer look at migrations and integrations

These are the projects where problems often sit outside the storefront: in the data, business systems and handoffs between processes.

Migration to Shopify and Shopify Plus

I review the current setup, decide with the team what to move or rethink, then prepare the data, redirects, testing and launch.

Shopify ERP and logistics integrations

I design the path taken by orders, products and inventory between Shopify and the systems that run day-to-day operations.

What the team keeps

  • A clear view of systems, flows and dependencies
  • Documented decisions, including alternatives and risks
  • A prioritised plan with clear ways to verify the outcome
  • Code, tests, monitoring and operating instructions

When it makes sense to involve me

When a technical decision spans several departments, a store has become difficult to change, or nobody is holding the business, suppliers and delivery team together.

From the first conversation to release, each phase should remove an uncertainty and make the next step easier to verify.
