For others on a similar path: courses, repositories, tools and opportunities worth your time.

The one paid course usually worth it: SQL, Tableau, Python and a capstone. My pick to go from "marketer who knows data" to "shows it".

Free, hands-on SQL from joins to window functions. The skill that separates you most from the average marketer.

Free official certifications for Google Ads and GA4. Table stakes, and the exams are quick.

Free SEO certifications from the two tools you probably already use. Easy, credible badges.

Free martech + CRM/lifecycle certifications. A cheap way to open the CRM/lifecycle path.

Open-source workflow automation. Where a lot of my marketing automation lives. HQ in Berlin, and they hire.

The framework this very site is built on. Ships almost no JavaScript — great for SEO and Core Web Vitals.

Free, English, hybrid tech education in Berlin (Data & AI track), eligible for migrants with a residence permit. A real on-ramp into data.

Free, well-made intro to AI from the University of Helsinki. A clean box to tick for AI literacy.
