About Joël

Hello,

Since obtaining my Master's degree in Computer Science from the École Normale Supérieure de Lyon, I have been a developer. I am primarily looking for medium or short-term assignments.

My key skills:
- Programming applications in Rust, Python, C++.
- Backend Web Programming.
- Django framework (with or without REST).
- Expertise in databases (SQL and noSQL).
- Expertise in cryptography (from my studies and internships).
- Development of complex algorithms.

My experiences:
- SCRUM backend programmer (database management, C++ Windows code maintenance) at Esker France.
- Agile website development for associations.
- Competitive programming (SWERC 2017-2018, Prologin 2013-2018).
- Research internships, notably within the GRACE team at the laboratory of École Polytechnique.
- Programming since the age of 13.

Thank you for your attention!
