Context
Access to housing in Paris tells a complex story of soaring prices per square metre, precious social housing and neighbourhoods in transformation. The "Urban Data Explorer" project aims to explore, understand and compare housing dynamics in the heart of the capital.
Our approach
The project builds a complete platform, from the data pipeline to map visualisation.
Data Engineering
Extraction of geolocated multi-source data (APIs, Open Data), cleaning, normalisation and geocoding. Storage is organised by processing layers (Bronze/Silver/Gold).
Backend
A high-performance web API for filtering by area, period or housing category.
Dataviz
An interactive dashboard with smooth navigation by arrondissement, including maps (choropleths and points), charts, a timeline and a side-by-side comparison mode.
Deliverables
A complete interactive web dashboard (pipeline, API, map front-end), built on open data, offering an accessible and intuitive view of the Parisian housing market.
