About

About

Hi, I'm Tolis — a Fintech BA with over eight years working at the intersection of payments infrastructure, digital banking, and European regulation.

My career started in the Netherlands at ABN AMRO Clearing Bank, where I worked on post-trade clearing, settlement, and regulatory compliance from the ground up. That foundation took me back to Greece, where I now lead delivery teams across complex banking transformation programmes — from instant payments and ISO 20022 migrations to open banking and compliance-driven system redesigns.

TheFintechBA is where I share what I've learned from the field — no theory, no fluff. Practical frameworks, honest takes, and real patterns from working inside European banking and Fintech projects.
