Team Profile

Senior BI Engineer & Excel Architect (6+ years experience)
Dur-e-Sameen works on the forecasting and amortisation side of the platform. Loan schedules, payment breakdowns and long-horizon projections are the models where a small structural mistake compounds quietly across hundreds of rows, and they are the ones she specialises in.
Her focus areas are finance and property, which on this site covers the mortgage, home equity and affordability tools along with the downloadable planners built to match them. The amortisation logic in those files is written to be read: every row shows how the payment split between interest and principal, rather than reporting only a closing balance.
She also builds the dashboard and Power Query side of the templates, so a file can take a user's own figures and re-present them without that user having to rebuild the model underneath.
