About

Nadia leads the personal finance desk and has spent over a decade writing consumer-facing explainers for banks, fintechs, and independent publications. She is obsessive about sourcing, formulas, and making the math feel approachable without dumbing it down.

She reviews every loan, mortgage, and budgeting calculator before it ships and is responsible for the editorial checklists the rest of the team uses.
