Meet ArtemSelected Upwork feedback from projects on these websites.
“He checked everything on the live site, found the actual cause … and rebuilt it properly so each enquiry only counts once.”

“He verified his fix with a real test order rather than just saying it was done, and was responsive and easy to communicate with throughout.”
“Artem did a fantastic job reconfiguring our GTM instance to work with OneTrust cookie consent.”

“Artem audited our web metrics setup, confirmed everything was working correctly, and created a Looker dashboard based on our goals.”

“He quickly identified a complex GA4 purchase attribution issue and implemented a reliable, well-documented solution.”

“Artem replies fast to messages and he completely solved our complex problem with our Meta Pixel. I apriciate that he communicates clearly!”
