Hi,
As a top rated freelancer on UpWork, I worked on dozen web, desktop and mobile projects; hired usability testers from USA/UK/Australia; developed test cases and test plans; managed manual testers; designed web/desktop UIs.
I learned interaction design and information architecture from UX guidelines and major books (by Steve Krug, Jacob Nielsen, Alan Cooper).
Related projects on Upwork are: "User Tester" (for UpWork itself), "Web Site Usability Testing", "Web software QA person needed", etc.
Lets talk via Skype,
Max.
