Back to original languageAbout Bertrand
After three years in consulting at 55 and more than a year in a French tech scale-up (Ankorstore), I decided to continue my activity as an independent.
My consulting experiences taught me to identify business opportunities, plan and operate the development of associated projects. For example, I worked on a car repurchase prediction project for a major car manufacturer, which increased CRM campaign conversion by 17% (A/B test performed).
As the first product analyst at Ankorstore, I first defined working methods, built A/B testing frameworks and defined analysis rules. Following these methods, I was able to provide the product team with:
- an exhaustive list of different product KPIs
- precise results from over 10 key A/B tests
- 5 dashboards (sigma) each meeting an identified business need
- over 10 deep dives leading to several high-impact recommendations.
Stack used: Python (numpy, SkLearn, pandas), SQL, GCP, Sigma.
