Description

Looking to transform your data into business performance levers?

For 11 years, I have been helping companies improve their product, margin, growth, and operational efficiency through data (particularly in SaaS, FinTech, and FoodTech).

My skills:

► Data Science: scoring, predictive models (demand, churn, conversion, closing)

► BI & Analytics: KPIs, dashboards, and data governance (SQL, Metabase, Looker)

► Data Engineering: pipelines & architectures (Python, GCP, BigQuery)

Some concrete results:

► FoodTech: multi-site forecasting pipeline (~10k/day) → –10% waste, +4 pts margin, scaling from 1 to 150+ sites.

► HR SaaS: dashboards & predictive models → ARR +80% in 8 months, ARR x3 in 2 years

► FinTech: AI identity verification product (3M operations/year) → –55% audit costs, +40% accuracy, +50% speed

What I offer:

► Implementation / optimization of data pipelines

► Design of predictive models (forecast, scoring, churn, etc.)

► Creation of KPIs/dashboards and structuring of data governance

► Audit & optimization of your existing data processes

My added value:
