About Wissal

You have data, but not always the insights that come with it. I help product, finance, and marketing teams turn their data into concrete decisions.

Data Analyst with 3 years of experience in e-commerce and marketplace (The Bradery, Malt), I work on the entire data chain: dbt modeling, operational dashboards, A/B experimentation, data reconciliation between sources, and deployment of LLM solutions in production.

What I build:
  • Steering dashboards on Metabase, Looker, or Amplitude (Finance, Ops, Marketing, Product)
  • dbt transformation pipelines on BigQuery
  • Reconciliation between systems (ERP, e-commerce, CRM)
  • A/B testing frameworks and performance measurement
  • Automated scoring and enrichment via LLM
Stack: BigQuery · dbt · SQL · Python · Metabase · Looker · Amplitude · Heap · Airbyte · Airflow

I integrate quickly into an existing team and deliver actionable analyses. Available for missions of 5 to 30 days.
