I reviewed your profile and have some suggestions. Your profile overview is short compared to the average. Upwork’s research shows clients see it as a positive signal if the profile is well written and comprehensive. Therefore, consider crafting your overview as a pitch to prospective clients.
Your written English skills are strong and you are easy to understand. However, I did see a few minor errors. If you'd like to add extra polish, you might want to consider using Grammarly. I use this myself and really like it because it's free and it offers a Chrome add-on so it works in webmail, messages, proposals, and more.
Here are some additional tips for writing a great Overview.
I hope this helps!
