Back to original languageAbout Rayane
I help scale-ups structure and make their data reliable to accelerate their business decisions
5 years in e-commerce scale-ups building solid data stacks: documented and tested DBT models, reliable pipelines, KPIs that business teams can truly rely on.
I step in when dashboards lie, no one trusts the numbers, or when the stack needs to evolve without breaking everything.
Last mission: GCP → AWS Migration for an international e-commerce scale-up — modernized stack, query time divided by 5, dashboards adopted by business teams in 3 months.
