About Valentin

Hello, I am Valentin, a Backend developer specializing in Java/Spring.

Graduated from an aeronautics engineering school (ENAC), I focused my training on programming but also on applied mathematics through a master's degree in operational research (optimization). After five years of experience in Backend web development in a Start-Up, I acquired and deepened the necessary skills for the profession by working on various projects, both in a team and individually (e.g., European TIINDAiR project). Familiar with the Agile methodology, I am very fond of this form of project management.

I can help you with your project on these different points:
- Web REST API Development
- Database design, creation, and migration
- API security
- Development of algorithms to solve complex problems (literature review, solution implementation, testing, simulation...)
- Writing tests for code robustness (unit tests, integration tests...)

I am friendly, open, and autonomous, and I integrate easily into a new work group. Naturally curious and eager to learn, I am enthusiastic about discovering new fields of activity and understanding their businesses. I regularly conduct technological watch which I apply to personal projects to always stay up-to-date and offer the best service corresponding to your requests. I am currently undergoing training in Frontend development (HTML/CSS and React.js) with a view to becoming a Full-Stack developer.
Do you have a new project that needs to get started, do you want to evolve your product or strengthen your development team? Are you looking for someone dynamic, serious, and concerned about the quality of their work? I would be delighted to discuss with you to see what we can do together.
