Google Tag Manager
Setup and audits of GTM containers: tags, triggers, variables and a clean dataLayer. Everything documented and validated against what really fires on the site, so you are not paying for duplicate or missing events.
Hi, I'm Stefan Vukobrat.
I help companies with
Digital Analytics
& Tracking
Google Tag Manager, GA4, server-side tracking and consent setups that measure what actually happens, not what everyone hopes is happening.
Brands I've worked with
- Sleek
- Serrala
- Bosch
- Hopmann Analytics
- LIQID
What I do
One focus: making sure the numbers you base decisions on are numbers you can trust.
GA4 & Product Analytics
GA4 and Amplitude setups built around the questions your business actually asks: events, conversions, funnels and reports your team will really use, instead of a default install nobody trusts.
Server-Side Tracking
Server-side GTM for first-party data quality: more reliable conversion data for Google and Meta, less data lost to browsers and ad blockers, and full control over what leaves your domain.
Consent & GDPR
Consent Mode v2, CMP integration and cookie audits. Measurement that respects user choices and keeps legal happy, without throwing away more data than the law requires.
Conversion Rate Optimization
Turning existing traffic into more customers: funnel and drop-off analysis, A/B testing and personalization, all built on measurement you can actually trust.
AI Automation
AI-powered automations for brands: marketing and CRM workflows, reporting and repetitive data work that runs on its own, so your team spends time on decisions instead of busywork.
Selected projects
A few client projects where I built the GTM and GA4 side of things.
Analytics and tracking work on Bosch digital properties: implementation and quality assurance of measurement at enterprise scale.
CRO and web analytics: I built and maintained the tracking framework (GTM, GA4, dataLayer and event tracking) behind A/B testing and personalization across websites, funnels and landing pages in multiple markets.
Global B2B payments software company. Web analytics and tracking work on the marketing side: reliable measurement for a complex, multi-market corporate web presence.
Analytics agency where I worked across multiple client brands: GTM and GA4 implementations, audits and ongoing measurement support.
German digital wealth manager. GTM and GA4 work on the marketing side: measurement a regulated financial company can stand behind.
Vitamax Nutrition
Supplement brand. I implemented the GTM setup and conversion tracking behind a CRO project: advanced segmentation and accurate conversion data across multiple markets. The client reports over 50% higher ROI within two months.
Website relaunch coming up?
A relaunch is where tracking usually breaks.
New design, new URLs, new stack: if measurement is not part of the launch plan, conversions and events quietly disappear on day one. I make sure your tracking survives the switch, with a measurement plan, GA4 and GTM set up on the new site, and validation before and after go-live.
And since everything is being rebuilt anyway, a relaunch is the perfect moment to move to server-side GTM: better data quality, less data lost to browsers and ad blockers, and full control over what leaves your domain.
Plan your relaunch trackingWhy work with me
You work with the person doing the work
From the first call to the last tag, you talk directly to me. No hand-offs between departments, no juniors learning on your project. One person is responsible for the result, and that person is on every call.
Measured, not guessed
I do not report a number I have not verified. Duplicate purchase events, consent gaps, broken funnels: those get found and fixed before anyone builds a dashboard on top of them.
End-to-end
From the dataLayer in the browser, through server-side GTM, to the reports your team reads. One person who understands the whole chain means problems stop falling between tools.
Plain language
You get proactive updates and documentation you can actually read. If a metric is unreliable, I say so, even when that is not the comfortable answer.
