About Razane

Data Science and Machine Learning Engineer, I build ML systems end-to-end; from raw data cleaning to production model evaluation.
I worked on real industrial data in the Oil & Gas sector, where I developed an intelligent planning platform using genetic algorithms, reducing assignment conflicts by 40%.

My projects cover classification, time series, deep learning, and recommendation systems.

I deliver documented notebooks, reproducible pipelines, and clear evaluation reports. Bilingual French/English, I adapt to startups and industrial companies alike.
