As part of my focus on education and standard adoption, I am the author of The Berlin Group openFinance API Framework Foundational course, designed to help professionals implement these crucial European standards.
Scheme² The Open Finance Blueprint
To further support the industry's transition to Open Finance, I authored Scheme² The Open Finance Blueprint.
This strategic toolkit offers an actionable framework for building the data-sharing schemes required by new European regulations. It provides a practical guide for banks, fintechs, and regulators on designing and implementing collaborative Open Finance ecosystems, turning a compliance challenge into a strategic opportunity.
