Download the database and normalize it
348 USD You need to download the Open source database file (the database of apartment sales and the database of apartment diagnostics) and upload it to the cloud database. Normalize their format, create a match between them, and provide me with an API so that I can make requests to it.
Database 1:
https://explore.data.gouv.fr/fr/immobilier?onglet=carte&filtre=tous
Database 2.
https://observatoire-dpe-audit.ademe.fr/donnees-dpe-publiques
I need to be able to search by address.
And the databases should be linked together based on the address, area, etc.

I am interested in your project. I can:
upload both databases,
upload them to a cloud database (for example, PostgreSQL),
normalize the format and merge records by address/area,
implement a REST API for address search with access to the merged data (Python).
On your database and on your server.

I have extensive experience with similar projects for the real estate industry. Recently, I implemented an identical system for a real estate agency in Spain with automation and AI.
My proposal for implementation:
Stage 1 - Analysis and data retrieval:
I will check the API limitations of both databases (there is often a limit, e.g., 100 requests/day)
I will retrieve full data from explore.data.gouv.fr and observatoire-dpe-audit.ademe.fr
I will conduct a data structure analysis
… Stage 2 - Normalization and integration:
I will create a unified SQL database (PostgreSQL/MySQL)
I will merge data by address, area, postal code
I will implement matching algorithms for incomplete addresses
I will create indexes for fast searching
Stage 3 - API:
REST API with address search
Filters: area, price, energy class, region
API documentation + testing panel
Rate limiting and security
Additional possibilities (optional):
🎥 Video automation - like in the Spanish project:
Automatic creation of videos with listings (30s for $0.25)
Realistic AI avatars (HeyGen)
Auto-publishing on social media
In Spain: TikTok 500k views in a month!
Technologies: PHP + n8n + SQL + API integrations
Execution time: 3-7 days (after analyzing API limitations)
Can we discuss the details? I am interested in the budget and whether you are also considering marketing automation with video?
