Open to full-time roles in Germany · from Nov 2026

Hi, I'm Anup. I'm a Data Analyst based in Berlin.

I turn messy enterprise data into dashboards, experiments and models that people actually use: 3+ years in data analytics, from BI at TCS to ML, RAG and LLM workflows as a working student, while finishing my M.Sc. at HTW Berlin.

01 / About

Numbers first,
then the story.

I studied mathematics and statistics, spent three years making CXO dashboards that leaders relied on, and now build ML and LLM systems that have to be measured before they ship. What ties it together: I care where a number comes from and whether it really supports the decision.
