The Journey So Far
Building clarity from complexity.
For over two decades, I've worked in finance across treasury, controlling, and financial reporting inside international companies, finding my passion at the intersection of finance and technology. I’ve always loved the challenge of untangling complexity, and for years, Excel was my tool of choice for creating clarity. Today, I’m channeling that same drive into learning more about data analytics and AI, looking for new ways to automate processes and build smarter financial systems. Curious, hands-on, and always learning.
