Strategic eCommerce Consulting Services

Technical Architecture & Systems

High-growth commerce requires a foundation that is both stable and agile. I oversee the structural decisions that define an enterprise stack, from leading complex Shopify Plus replatforming and migrations to auditing legacy infrastructure. By aligning technical architecture with business goals, I ensure your technology accelerates growth rather than creating debt.

Internationalisation & Global Growth

Scaling globally is a strategic operation, not just a technical one. I help brands navigate the complexities of international expansion, from localised checkout experiences and multi-store architecture to regional fulfilment logic. My focus is on removing friction in new markets to unlock sustainable global revenue streams.

Conversion & Customer Journey

A high-performing store is the result of a seamless end-to-end experience. I focus on the intersection of discoverability and user experience, ensuring brands are visible in an AI-driven search landscape while optimising the onsite journey for conversion. By refining how customers find, navigate, and interact with your brand, I drive top-line revenue through meaningful digital experiences.
