About Toni

With over 9 years of experience in digital analytics, conversion rate optimisation (CRO), and user experience (UX) strategy, I help businesses make smarter decisions through data. I’ve worked across diverse industries supporting startups and large enterprises alike in turning customer insights into measurable business outcomes.

My expertise spans the full data lifecycle—from implementing robust tracking solutions to generating actionable insights that drive revenue and enhance user satisfaction. I'm highly proficient in tools such as Google Analytics, Tag Manager, Data Studio, Looker, Power BI, and CRO platforms like Google Optimize and VWO. I’ve led A/B and multivariate testing programmes, built end-to-end reporting suites, audited analytics frameworks for compliance and accuracy, and collaborated closely with product teams to improve digital performance.

I'm passionate about combining technical analytics skills with a deep understanding of customer behaviour to streamline journeys, reduce friction, and deliver compelling user experiences that convert.
