2021 – 2022Berlin, GermanyBusiness Analyst

Retention analytics for a Berlin-based B2B SaaS recruiting platform. Built the data infrastructure and analytical layer that made customer-level signals more complete and more timely.

What I Built

Attribution Pipeline

Built ETL and EDA pipelines that expanded attribution data coverage by 200%, giving product and growth teams a materially more complete picture of where customers came from and what was driving conversion.

Churn-Action Timing

Improved the timing accuracy of churn-action signals by 83%, surfacing the right early-warning indicators earlier in the customer lifecycle, when retention intervention is still effective.

Recurring Revenue Analytics

Applied ARR/MRR analytics and cohort analysis to subscription data, building the analytical foundation for understanding growth, churn, upsell, and retention at a product level.
