About Louis

Data Scientist and biostatistician with over ten years of experience at the intersection of health, research, and software systems.

I support teams and organizations in structuring, exploiting, and leveraging complex data, applying artificial intelligence, and developing large-scale analytical systems.

My work focuses particularly on:
• designing robust data pipelines and analytical infrastructures;
• extracting, structuring, and validating complex documentary data;
• OCR / NLP workflows and document reliability systems;
• monitoring, analysis, and decision support tools in clinical and health environments;
• developing applications and systems focused on real-world use and operational continuity.

I have worked alongside clinicians, researchers, software engineers, and product teams in hospital, public, and technology settings.

I favor pragmatic approaches, reliable systems, and solutions designed for sustainable, large-scale use.
