What I'm looking for

I'm looking for UK-based, remote or hybrid work.

At Quirky Digital, I led technical SEO strategy and delivery across the agency's client portfolio, turning audit findings into prioritised roadmaps and developer specifications. I also advised clients on migrations and presented technical findings to non-technical stakeholders.

At 120Feet, I managed day-to-day analytics delivery for organisations including Tesco and Auto Trader, translating measurement needs into implementation instructions and testing tracking across complex websites. Now, as a freelance SEO and Analytics Consultant, I provide technical SEO, analytics, conversion-tracking and marketing-automation consultancy, including GA4, server-side tracking and GoHighLevel workflows.
