Freelancer profile translated to English.

Description

Madam, Sir,

As a graduate engineer in industrial computing, I am passionate about embedded technologies, IoT, electronics, and full-stack development. Through my academic and personal projects, I have acquired solid technical expertise that I now wish to put at the service of your company.

I have designed complete intelligent systems based on microcontrollers such as the ESP32-S2, integrating water level, humidity, and battery sensors. I ensured wireless communication via LoRa and the MQTT protocol, with transmission to the cloud via AWS IoT Core. For visualization, I developed dynamic web interfaces in ReactJS, connected to a backend API designed in Flask, allowing real-time and historical data tracking.

I master the design of printed circuit boards (PCB), electronic simulation tools, as well as energy consumption constraints (deep sleep). I also have good knowledge of electromagnetic compatibility (EMC) and industrial standards. In addition to this, I have skills in project management, technical communication (fluent English, professional French), and the development of robust and scalable solutions.

Autonomous, curious, and motivated, I am ready to take on new technical challenges and actively contribute to your innovative projects.

While awaiting an interview, please accept, Madam, Sir, the expression of my distinguished greetings.
