Passion brought us here…that’s the reason why you, as a business owner or director and I doing business together.

I worked for major companies such as ING and PGGM Investments, which manages AUD 450 billion in assets. I also run my own investment and finance consulting business, HD Investment & Finance Consulting as well as CoffeeBagArt, where we create sustainable home décor and furniture from coffee bags.

Running a business comes with plenty of challenges—cash flow, planning, growth, risk—and that’s where I come in. I offer practical, down-to-earth advice tailored to your business goals. Whether you’re looking to understand your numbers better, manage costs, plan for the future, or just make smarter financial choices, I’m here to help.

I take the guesswork out of your finances by using clear reporting, simple explanations, and data-driven tools to give you real insights—not just spreadsheets. I’ve worked with everything from large datasets to advanced platforms like Power BI, SQL, and Python, but my focus is always on what matters most to you: results.
