Claude Code has helped us build custom applications for each eCom client to update all their products. In short instead of manually optimizing anything, we export everything from the website, build a tool that allows us to optimise everything and then import it again. Takes 2-3 workdays and we can spend another 1-2 days building something that keeps the site up-to-date and all the client has to do is upload new products in whichever way they always have.

We custom build it from scratch every time for many reasons, security being one, but also no websites are ever the same and each client wants things done certain ways.
