Hello, my name is Oleg.
7 years ago I left Qualiteam(Company who created X-Cart) where was on the second position in top from over 80 developers. 7 years I was working on free-lance sites like Elance and Upwork(oDesk).
To verify it - see verified "Employment" section on my Elance account page (it's in the bottom)
Also I have profile on Upwork
I provide X-Cart 5 and 4 E-Commerce development and others.
Over 100 full online stores and more just with customizations(Design experience is about 4 years and not always I get hired for design). For references and more work examples contact me directly.
