Valentin Lerouvillois

Passionate Full Stack Developer, I design and develop modern web and mobile applications, from the user interface to the API and database.

Through my corporate experience and my various professional and personal projects, I have worked on applications using Angular, React, NestJS, Java Spring Boot, PostgreSQL, MySQL, and MongoDB. I place particular importance on code quality, testing, security, and application maintainability.

I am involved in creating complete applications, adding features, fixing bugs, optimizing performance, or taking over existing projects.

I also use artificial intelligence tools professionally to accelerate certain development tasks, improve code quality, generate technical documentation, automate repetitive processes, and increase productivity while maintaining rigorous human validation.

My areas of expertise:

• Front-End Development (Angular, React, TypeScript)

• Back-End Development (NestJS, Java, Spring Boot)

• Database Design and Management

• REST APIs

• Web and Mobile Applications

• Docker and Deployment

• Maintenance and Evolution of Existing Applications

• Unit and Integration Testing

Serious, responsive, and involved, I prioritize clear communication and regular follow-up to ensure the success of the projects entrusted to me.
