Artem Ponomarenko
Data Analyst · Munich, Germany
I'm experienced in large-scale analytics and ETL pipelines, turning messy data into insights that actually get used.
Also I have strong background in applied math and ML. I run experiments, build forecasts, and fix data pipelines that keep breaking.

Data Analyst · Nov 2023 – Sep 2025
Worked on user-matching at massive scale, handled billions of nodes across platforms. Ran experiments with product and ML teams to improve ad targeting. Built a sociodemographic data mart that became the go-to source for ML and ads teams. Automated NPS reporting so nobody had to do it by hand anymore.
