There are a thousand and one ways to communicate. What if sending a message to someone you know becomes even easier? The idea of Blink is to offer via a capacitive sensor the possibility of sending a message to the person of their choice. The bracelet is however only the material part of the project. A smartphone application must be developed. Flutter framework was thus chosen. The connectivity between the smartphone and the bracelet is ensured by Bluetooth connectivity. The electronic circuit of the bracelet is designed to be very energy efficient. The processor is a chip from STMicroelectronics, which contains the firmware of the bracelet.

This educational project, as part of a teaching unit at IMT Atlantique to touch on the issues of modeling, design, creation and development of an object.
This project is originally a response to the call for applications made by CNES for projects to be tested in micro gravity. Unfortunately Astre, the robot arm was not retained by CNES.

This project offers via a web server written in NodeJs a simple REST API (CRUD) allowing to interface directly with a MongoDB database.

Docker is very present today and compatible with most platforms. However, it sometimes happens that Docker engine cannot run on the machine in question. If it is compatible with LXC containers, then it is possible to launch containers. But why not take advantage of Docker's flexibility and hundreds of pre-built images?
By a set of script written in bash, this project offers a possibility to do almost everything as with docker without having docker It is possible to download and launch images from the hub. To create these own images, ...
Under the hood, everything is written in bash, uses IPTables to open ports and redirect to services, a shared host file for the names of instances and local IP correspondence.
In four years of personal use, the tool has enabled approximately 20 images to function.

Implementation in the JDBC connector for SQLite of compatibility with encrypted SQLite databases. The use of this library remains compatible with the original library. Several encryption possibilities are available:

• wxSQLite3: AES 128 Bit CBC - No HMAC
• wxSQLite3: AES 256 Bit CBC - No HMAC
• sqleet: ChaCha20 - Poly1305 HMAC
• SQLCipher: AES 256 Bit CBC - SHA1/SHA256/SHA512 HMAC
• System.Data.SQLite: RC4

This website, my portfolio, is itself a project. It is written in HTML5, Javascript, CSS. It is generated by NodeJs and Gulp. The CVs in PDF format are also self generated from the website. The information between the two media is therefore always perfectly synchronized.

This project provides a simple widget on Android for entering, formatting and syntax validation of phone numbers in an Android application.

Packet3Sous is a network simulator created during an educational project. The idea is to reproduce in a simplified way the operation of the Cisco packet tracer network simulator. The implementation of this simulator reproduces the theoretical behavior of equipment such as hubs, switches or routers. For this, the MAC, IP and Transport layers of the OSI model have been implemented.

Originally designed as an extension for the Clangue project, it is an application enabling simple video editing from your web browser using HTML5 technologies. The final rendering of the video is calculated on a server using the FFMPEG tool.

Platform for simplified learning of foreign languages. The platform was designed in collaboration with the language teachers of the Simone Veil high school in Valbonnes to best meet their needs. This allows continuous speaking, multiple choice questions, video editing as well as written expression. This platform has been used by more than 500 students from Simone Veil high school in Valbonnes for almost 2 years.

Genetic drift simulation application written in Javascript used in high schools to replace a previous version written in flash.
