About

From optimising pages to measuring the business

I started in technical SEO thinking my job was to make Google understand my pages. I ended up writing Python pipelines to pull data from the Search Console API, modelling experiments and publishing dashboards. That shift, from optimising pages to designing the infrastructure that measures them, is what took me to the master's in Big Data & Cloud. Before data there were eight years of marketing, market research and auditing, and that is where the business judgement I bring to every model comes from.
