Start with a real problem. Keep the solution simple.
I pair product management with data analysis: understand the need, find where people get stuck, and help a team focus on the changes most likely to matter.
My background spans conversion analysis, agile product delivery, Python ETL, and a Master’s in Data Science and Business Analytics. I use that toolkit across projects in business operations, local discovery, and personal finance.
