Vell

Vell est une start-up ayant levé 2 millions d'euros pour vendre le véhicule de particuliers à leur place. Mise en ligne de l'annonce, organisation des visites et tiers de confiance au moment de la vente.

Problem

The company is experiencing strong growth and is facing significant operational challenges, especially when it comes to managing ads. Indeed, the publication of an announcement on Leboncoin and La Centrale via the public graphical interface is particularly time-consuming when it comes to processing hundreds of them.

Vell is therefore looking for a solution to optimize this process and save time. Since the project is young, the internal technical team does not have the bandwidth to manage everything. Vell is therefore asking us to offer them an adapted solution.

Solution

After fully understanding the Vell operational tunnel during a videoconference with the team, we propose the development of several tailor-made tools to simplify their processes:

  • An ad multicast API that allows you to publish, unpublish and update an ad on several sites simultaneously (Leboncoin + La Centrale) in a single request.
  • A web interface for salespeople to easily interact with the API.
  • An administrator back office allowing you to view all the online ads stored in the database.

The API, the core of the system, is developed in Node.js + TypeScript and deployed on Google Cloud Run, ensuring automatic scaling according to demand. The architecture was designed to allow the startup to easily integrate new online ad presenters in the future, while ensuring the sustainability of the connectors with Leboncoin and La Centrale. A robust error management system has also been put in place to quickly identify any synchronization issues.

The web interface was first developed on Retool for quick implementation, then on Bubble to improve the user experience.

Finally, we used Airtable's “Interfaces” feature for the administration part.

The project was deployed in less than two months, allowing Vell to actively relaunch its recruitment!
