A project from scratch: design, then development. The site needed to run in multiple languages, with the same content structure in every version, and a language switch that doesn't bounce visitors back to the homepage.
The project started from a blank page: design, then development. The product range needed to show in multiple languages, and the language versions had to stay paired as content kept growing.
I set up language versions so every page translates in pairs, with separate SEO fields per language and an admin where a new language version gets added without development work.
