I am Raffo Sarkiss.
Previously, I was the Head of Growth Operations & Business Intelligence at Qonto, a 500-person fintech that raised €135 million in funding. I manage a team of 4 data analysts. This has allowed me to install or use powerful data visualization tools like Metabase or Tableau and to work on Postgresql databases or Warehouses like Snowflake. My expertise allows me to teach beginners the art of SQL and data analysis in a simple, fun and multi-step way:
1- Installing a database with PGAdmin, a data visualization tool with Metabase and a server with Heroku.
2- The basics of SQL3- Building graphs and BI dashboards for a first step in the world of data visualization4- Advanced SQL to meet business needs (cohorts, median, quartiles, series generation etc...)
