Hello
I have read your demands carefully, and for start, i have to say that i am really interested in this project, but there might be some minor issues, like: I am from Serbia, and even that we also must follow GDPR by our own law (we have it same as rest of EU even we are still not member of it) and i am ok with HTML, CSS, JS and Wordpress, some PHP too, but i am dull for Drupal and Shopify (never had to work projects based on them).
If you do not mind those two minuses too much, maybe i can be a nice add to your team, since i am looking for some long-term engagement (had one, for few years, but that Australian guy got huge project from the government and left freelancing completely)...
Also, have a friend who was working with me, same skills, maybe a bit better with PHP ans CSS, but also mostly Worpdress based work, and in case of any need, you can count on two of us...
Feel free to contact me if you have any questions.
Regards,
Steve
