As a web developer at Matelex, I worked on an innovative platform for managing refrigeration installations using big data from connected objects, called Polarbox, to monitor equipment status in real-time.

Company Presentation

O’Cleaner has been in business since 2020. It currently operates a laundry service in Boulogne-Billancourt 92100, with high-performance machines of various capacities. It also offers on-demand laundry cleaning services for individuals and textile care products.

The Challenge

O’Cleaner (Eco-Friendly Laundry) witnesses the effort people put into managing their laundry: between waiting at self-service laundromats and the long journey to pick it up, the options are not always convenient.

This led to the idea of O’Cleaner Delivery: a courier picks up laundry from the client's home and returns it, washed, dried, folded, and ironed according to their preferences. The goal is now to bring this idea to life with a mobile application, an e-commerce website, and a supervision website. They have therefore engaged our services for the design and development of this solution.

Application Objectives

Our O’Cleaner Delivery application will address these previously mentioned problems: it will simplify the daily lives of users who will no longer need to travel, transport their clothes, or clean and iron them themselves. Thanks to the delivery service, they will be able to select a time slot in just a few clicks and have their laundry delivered to their door at their convenience.

This solution will include:

- A mobile application and website accessible to users to select laundry packages, delivery slots, and track orders with delivery stages.

- An application accessible to delivery personnel to update delivery tracking in real-time.

- A web supervision interface to provide complete order and delivery tracking, manage pricing and packages, and manage employee profiles.

- A REST API
