About Wissal

Vous avez de la data, mais pas toujours les insights qui vont avec. J'aide les équipes produit, finance et marketing à transformer leurs données en décisions concrètes.

Data Analyst avec 3 ans d'expérience en e-commerce et marketplace (The Bradery, Malt), j'interviens sur l'ensemble de la chaîne data : modélisation dbt, dashboards opérationnels, expérimentation A/B, réconciliation de données entre sources, et déploiement de solutions LLM en production.

Ce que je construis :
  • Dashboards de pilotage sur Metabase, Looker ou Amplitude (Finance, Ops, Marketing, Produit)
  • Pipelines de transformation dbt sur BigQuery
  • Réconciliation entre systèmes (ERP, e-commerce, CRM)
  • Frameworks d'A/B testing et mesure de performance
  • Scoring automatisé et enrichissement via LLM
Stack : BigQuery · dbt · SQL · Python · Metabase · Looker · Amplitude · Heap · Airbyte · Airflow

Je m'intègre rapidement dans une équipe existante et livre des analyses actionnables. Disponible pour des missions de 5 à 30 jours.
