The technical laboratory of Ceylan Belin — MarTech Strategist building from İzmir, thinking in Copenhagen and Brussels. Sovereign Core was born here.
This is the Lab — where every experiment starts. From early data notebooks on sustainability, to the behavioral entropy models that became Sovereign Core. It is a record of how ideas become infrastructure.
Built entirely from mobile. No desktop, no agency budget. What you see here is a real stack: server-side infrastructure running 24/7 on Render Frankfurt, GTM containers across four live domains, and a GDPR-compliant intelligence layer written from scratch.
Target: a single European organization in Denmark or Benelux that takes data governance seriously. Sovereign Core comes with me — from day one.
MarTech Strategist & Data Engineer · Creator of Sovereign Core
I hold certifications in GA4, Google Ads Search, Google Ads Measurement, GTM, and Privacy for Agencies & Partners. My background spans B2B sales, corporate marketing, trade fair operations, and digital strategy.
I built the Smyrna & Sable brand concept from scratch — and with it, a full ecosystem: Smyrna & Sable (the brand), Smyrna & Sable Shop (multilingual e-commerce), Smyrna & Sable Lab (the strategy laboratory you are reading now), and Sovereign Core — a server-side marketing intelligence platform designed governance-first, running 24/7 on EU infrastructure. Five phases completed. Eight modules. Built entirely from a mobile phone, with zero budget.
This ecosystem is proof of capability — not a claim. I am looking for a single European organisation in Belgium, Denmark, or the wider Benelux and Nordic region where I can be a 360-degree partner: strategy, data, infrastructure, and governance. Think of me as a Swiss Army knife. When you hire me, Sovereign Core comes with me. From day one.
Europe's first server-side marketing intelligence platform. Real traffic. Real data. Running now.
Europe's first server-side marketing intelligence platform. It protects your advertising budget, keeps your data in your own hands, and measures the carbon footprint of your digital operations.
Every line of code started here. The Waste Oracle experiments in this Lab became the detection engine. The consent signals became Privacy-Preserving Audience Intelligence (PPAI). The weekly audit logs became Carbon Tracker.
