CRO · SEO/GEO · Liquid · Migration · Data
I connect strategy, buying experience and technical execution to turn Shopify stores into clearer, measurable and maintainable growth systems.
Founder of EXPERAISE · Independent consultant · Arras · Paris · Remote
A hybrid profile to stop decisions getting lost between strategy and technology.
I work where Shopify stores slow down: unclear positioning, overloaded buying journeys, theme debt, fragile indexing, risky migrations or insufficient measurement. My role is to isolate the real problem first, then connect the commercial decision to its implementation.
I can analyse data, prioritise a roadmap, design the experience, work in Liquid and the theme, then document validation. This continuity reduces hand-offs between consulting, design, SEO and development.
EXPERAISE lets me bring in a collective when an engagement requires several specialists. I remain an independent consultant, accountable for my scope, recommendations and their level of evidence.
I prefer one measured, maintainable decision to a stack of new features.
Five areas of expertise, one decision system.
Each area solves a different problem. They are brought together because serious Shopify improvements often touch several layers at once.
- CRO & UX : Identify the friction that prevents understanding, choosing or buying. Mobile audit, journeys, PDP, cart, impact × effort prioritisation and measurement protocol. View CRO support
- Shopify SEO/GEO : Make strategic pages crawlable, understandable and citable. Architecture, internal links, structured data, Markets, hreflang, Search Console and AI visibility. View SEO/GEO support
- Liquid & themes : Build inside the storefront without stacking unnecessary dependencies. Custom sections, Shopify 2.0, performance, accessibility, QA and documentation. View Shopify engagements
- Migration : Change platform without sacrificing data, SEO or commercial continuity. Mapping, redirects, content, catalogue, tracking, QA and launch plan. View the migration method
- Data & validation : Define what must be measured before claiming a result. GA4, Search Console, events, sources, measurement periods and documented limitations. Explore my method
From hypothesis to evidence.
A useful engagement does not end with a list of recommendations. It ends when the team knows what to decide, how to verify it and how to maintain the result.
- Observe : Data, journeys, code and real constraints before any solution.
- Prioritise : Expected impact, effort, risk and level of evidence made explicit.
- Build : Theme implementation or specifications the team can use immediately.
- Validate : QA, measurement, documentation and an honest reading of what is or is not proven.
Engagements explained with their context and limitations.
I separate measured outcomes from delivered work. Case studies state the exact role, scope, measurement period and data source.
- Nutripure : +34% GSC impressions over eight weeks. ES/IT hreflang, JSON-LD, crawl, performance, over 2,700 images and Search Console checks. Eight weeks vs the previous eight · GSC source. Read the Nutripure case
- Second Step : A prioritised roadmap and execution-ready quick wins. Mobile and desktop audit, buying journey, reassurance and impact × effort ranking. Verified deliverable · no uplift claimed. Read the Second Step case
Publish what I can explain, date and verify.
