Description

Hello,

As a computer scientist and Data Scientist today, I previously worked in the naval industry as an electrical design technician and site supervisor. It was during this experience that I grasped the strategic role that IT and data analysis can play.

Thus, I decided to resign to pursue an in-depth university degree in mathematics-computer science, including a specialization in Data Science, from bachelor's to master's level. Thanks to my studies as well as my personal projects and various explorations, I have acquired solid expertise.

However, I note with regret that despite the many advantages they offer, these techniques remain under-exploited. That is why I strongly encourage you to take an interest in them. I am at your disposal to discuss and help you clarify the possibilities offered, in order to determine together the concrete benefits they could bring to your project.

My expertise covers a wide range of essential technical skills, which would allow me to bring significant added value to your projects.

These include:

Programming: Python / C++

Data Science: Numpy / Pandas / Pytorch / Scikit-learn

Visualization: Dash / Plotly

API: Flask

Database: SQL / NoSQL

My desire to contribute to ambitious projects makes me an ideal collaborator to achieve your goals in the field of data science.

Sincerely,

Yoan Belleperche
