Based in Ticino, Switzerland · nLPD and GDPR compliant setups for Swiss and EU businesses
Tracking you can trust. Consent you can prove.
I build analytics, tag management and cookie consent setups for e-commerce and lead-driven businesses, so your data is accurate and your website respects privacy rules.
Try it: what happens when a visitor chooses
A simplified example of consent-based tag firing (Google Consent Mode v2).
Services built for e-commerce and lead generation
Analytics setup and audit
GA4 and Google Tag Manager built from a clear measurement plan, or a full audit of what you already have.
Consent and privacy
Cookie banners on OneTrust and other platforms, Google Consent Mode v2, and tags that fire only after the right consent.
Server-side tagging
Server-side Google Tag Manager for first-party data collection: more complete data, faster pages and better control over what leaves your site.
Ad platform tracking
Google Ads, Meta, TikTok and other pixels set up so ad reports match what really happened.
E-commerce and lead tracking
Product views, carts, purchases, calls and form submissions tracked end to end and checked against your real data.
Reporting and BigQuery
Raw data in BigQuery and clear dashboards in Data Studio.
Websites

Common questions
Which platforms do you work with?
Mainly OneTrust for consent, plus other consent platforms, Google Tag Manager (web and server-side), GA4, BigQuery, Data Studio, Google Ads, Meta and TikTok.
Can you work across several countries?
Yes. I have experience with several brands and markets, where consent wording and rules can differ, including US setups for CPRA opt-outs and Global Privacy Control.
How long does a typical project take?
A focused audit or setup usually takes days, not months. You get a timeline in the quote.
Do you give legal advice?
No. I implement your consent setup technically. Legal wording should be confirmed with your legal team.
Does this website track me?
No. This site sets no cookies and loads no third-party scripts, so it needs no cookie banner. When tracking is added, it will run through a consent-first setup you can inspect.
