I read the story hidden in the data.

I'm Sarah Khan. I turn customer behaviour, survey feedback and sales figures into recommendations that people act on. Trained in business in Karachi, now completing an M.Sc. in International Business Economics in Germany.

About

Curious about why people buy, switch and stay.

I started in business administration at the Institute of Business Management in Karachi and spent two years at Chemli Private Limited, first as a market research assistant and then as a customer insight analyst. There I ran pre-launch studies for new household products, analysed the behaviour of more than 20,000 customers, and presented recommendations to the board of directors.

In 2024 I moved to Germany for an M.Sc. in International Business Economics. Alongside the degree I completed the IBM Data Analyst Professional Certificate and the AWS Cloud Practitioner exam, and I am now working through Stanford's Supervised Machine Learning course.

What I enjoy most is the moment a messy survey export turns into a single chart that changes a decision.

Have data that needs a second look?

I'm happy to talk about working-student roles, research collaborations or a dashboard that isn't telling you what you need to know.
