I'm offering
I am a Google Cloud Certified Professional Data Engineer with experience across all areas of data, from analytics and insight to pipeline engineering, data structuring to data science. I strongly believe that data should be at the heart of every organisation, that it should be there to make business decisions and looking forward, not for reporting and looking back and that every team in the company should have access to and be empowered to use data in their work.
I am the author of a number of GTM custom templates available in the GTM template library and have just released an alpha version of a Google Tag Manager R package, googleTagManageR.
I'm also a keen skier, scuba diver and climber and love the outdoors. I've been volunteering with Protect Our Winters UK as the head of data and digital since January 2018, working on optimising existing assets, developing actionable campaigns that deliver measurable results and increasing the quality and quantity of content we're producing as well as developing the website to deliver a B2B engagement campaign launching next year.
