What I'm looking for

I seek a data-focused marketing analytics role where I can lead media measurement, improve attribution, automate reporting, collaborate cross-functionally, and drive measurable ROI and scalable growth.

I am a data-driven marketing analyst with over four years' experience in SaaS, fintech, and retail media measurement, specialising in performance marketing, commercial analytics, and campaign optimisation.

I build and validate Marketing Mix Models, run geo-lift and incrementality experiments, and design attribution frameworks using tools like Facebook Robyn, Python, R, and GA4 to improve ROI and reduce media waste.

I create self-service dashboards and automated reporting in Domo, Tableau and Power BI, streamlining access to insights and reducing ad-hoc requests while supporting senior stakeholders with actionable recommendations.

I collaborate across product, engineering and growth teams to improve tracking, lead scoring and customer journeys, documenting learnings and automating processes to support scalable growth and better marketing outcomes.
