At Betclic, I make data talk: modeling, dbt and SQL transformations, data products and dashboards for business teams, with a little help from generative AI. On the side, I code a lot for myself: an everyday need, a blocker that bugs me or just an idea worth trying, and it turns into a project. I like trying things, getting it wrong, finding the fix… and starting again.
