Financial analyst at ExperTrade S.A.C. who designed an Excel loan management system with transparent repayment schedules.
What I'm looking for
At ExperTrade S.A.C., I designed and implemented a loan management system that gives clients readily available repayment schedules and transparent loan calculations using Excel.
I also developed a loan simulation model with Excel macros and VBA to project cash flows and revenue streams, supporting long-term financial planning and business sustainability.
At Leeds Finsights, I wrote three economic articles for a newsletter with 500+ subscribers, exploring subjects including developing economies and UK policy. I received training from an award-winning Financial Times editor.
For my BSc Economics dissertation at the University of Leeds, I used Stata and a probit model to examine regional determinants of in-work poverty in the UK. I’m interested in applying economic research and financial analysis to practical decisions.
