πŸ’Ό Background

Before pivoting into tech, I spent years in finance and administration β€” managing budgets, reporting on business performance, and working with data every day in Excel and financial systems. That experience gave me a strong business instinct: I don't just build charts, I ask what decision does this data need to support?
