Editing and optimizing a store on OpenCart 2

I am looking for a specialist who has experience with stores on OpenCart. We are using version 2.3.0.2.

Most of the tasks are simple ostyling - padding, fonts, etc., but there will probably be some more technical ones. The store has been running for a while, but I'm running optimization now.

I ask only for offers with examples of supported stores.

Remote work, on an hourly basis. If we are very satisfied, there is also a potential possibility of permanent employment.

Knowledge of marketing basics, GTM, SEO, UX, Google Merchant is welcome.

Working with young people, relaxed atmosphere, no pressure, but ambitious approach to tasks.

Please quote a month of work for the declared number of hours.
