Those my clients from Upwork or that have found me directly, usually leave their reviews in Facebook, LinkedIn or wherever they have found me.

Very well done, 100% committed to the job. I’ll recommend her to anyone that needs an SEO audit.
Olesia has conducted preliminary technical audit and guided us through technical optimisation process for SEO purposes. Her meticulous approach and thorough attention to details have helped us a lot with smooth transition of our website to another domain and CMS. Among her strongest points are concentration on long term results rather than short term, and keeping in close touch through the whole process. Strongly recommend!
