As the newly minted "Craft Guy" when I joined Studio24, it was my job to take over the CraftCMS rebuild of the Cambridge Trust website that was in progress when I joined.
I saw the project through and got the new Craft build deployed to production. This build involved a bit of data migration too, as it saw me getting data from not only a custom-built CMS that Studio24 had built previously for Cambridge Trust, but also an older build of the site in Expression Engine!
