About Carine

Analytic developer and consultant, I designcustom toolscombiningweb development(Symfony/PHP),automation(Python), anddata processing(textual, geographical, or business data), with particular expertise ininteractive dashboardsand **web mapping**.

I undertake **targeted data-related missions**: automation of processes (Python), data visualization (Power BI, Qlik Sense), web tool development, and creation of interactive Web GIS modules for representing geographical indicators (Leaflet, GeoJSON).

My expertise notably covers automatic language processing (NLP), verbatim analysis, and sentiment classification.

Thanks to my background in **sociology**, I bring a nuanced understanding of qualitative data and user expression patterns. This dual expertise allows me to bridge the gap between actual usage, business needs, and technical solutions.

I develop automation scripts and build complete cleaning, modeling, and visualization pipelines. I work on both new projects and the improvement of existing tools (intranets, dashboards, forms, reporting).

With solid experience in the public sector, I have led concrete projects related to geographical data, user verbatim, and business tools, in direct collaboration with field teams.

I enjoy designing useful, stable, and well-documented solutions to meet user needs.

I offer onlyone-off, well-defined missionswith concrete deliverables, on which I can work autonomously.

Available approximately 2 days a week, I prioritize targeted projects that require rigor, a clear vision, and a tailor-made technical approach.
