About me

Hi, I'm Vasili. I fix and build tracking in GA4, GTM, and BigQuery. I help SaaS and e-commerce companies get data they can actually trust.

What clients come with: GA4 numbers don't match CRM/Google Ads, need to implement server-side GTM (Cloud Run/App Engine on GCP), gaps in Meta/LinkedIn/Google Ads CAPI, GA4→BigQuery export broken, product events (onboarding, subscriptions) missing from the data model.

I work end-to-end: dataLayer inspection → GTM fix → validation in Realtime and BigQuery. You get a report: what was done, what was fixed, what to watch.

Experience: mid-size and enterprise clients in retail, e-commerce, legal/publishing, industrial (under NDA). Recent: event-tracking for a SaaS in the GBP space — full Kali Forms → GA4 field mapping, debug + QA.

Training: GA4, GTM, Looker Studio — online (100+ participants) and on-site.

Stack: GTM (web + ssGTM), GA4, BigQuery SQL, JavaScript, Meta/LinkedIn/Google Ads CAPI, GCP, Looker Studio, CookieYes/CookieBot.

Languages: PL, EN, RU. I reply
