Jan Vorjohann

I am passionate about providing actionable data-driven solutions and have established myself as a UK-based Data Scientist with a proven ability to deliver relevant insights and products.

With over 10 years of experience in the payments industry, I combine hands-on technical expertise with strategic leadership to create business value. Since joining London-based Trust Payments in 2021, I've developed innovative products including ProbH, CryptoMetrix and TrustGPT, while supporting the organisation with profound AWS deployment skills and implementing best practices for automation with Generative AI and integration tools like Workato. During my 7 years in the Co-Branded Credit Card business in Berlin, Germany, I led a large-scale Data Warehouse and Business Intelligence transition and drove the organization's evolution toward data science, while expanding the team from 3 to 7 members.

My work with advanced machine learning models has allowed me to create solutions that process over 50 million transactions, helping protect vulnerable customers and supporting regulatory compliance in the payments ecosystem.
