I would advise to work more on the Title and Overview sections of your profile. Upwork gives good suggestions how to fill sections while you are in edit mode on these sections. Also check other freelancers profiles for examples and ideas. You might also add more projects into Portfolio with detailed descriptions of what technology stacks were used. Availability can be set to the maximum of available hours you have for the moment.
Clients usually look for experts in particular technology or stack. Imagine the needs of your ideal (but real world) client and develop your strategy to show up as an expert and right person to complete the project. Your profile's Title and Overview might become more specialized in some particular technologies where you are experienced the most, for example, "Expert Full Stack developer highly experienced in Wordpress".
Great job on other parts of your profile so far!
Alexis - when a client first sees your profile, they only see the first two lines before they decide whether to scroll down. Lose the introduction. Go straight into your experience and expertise.
