About Julien

Young Bordeaux native, I joined Paris in 2018 when I enrolled at the École Polytechnique. It was there that I began to develop an interest in programming, particularly in Computer Vision. I then pursued training focused on this area, as well as Machine Learning and Deep Learning. After graduating, I worked as a freelancer for a few years.

It was through my various internships and freelance experiences that I was able to further develop my knowledge and skills. By focusing heavily on Deep Learning for images and videos, I learned a great deal and specialize in this field, quickly providing solutions for image/video classification, detection, or segmentation problems.

I have primarily worked for various clients and am capable of supporting them from data collection/annotation, to the development and training of the most effective and suitable model, and if necessary, to the deployment of an application for testing and evaluating my models' performance.

I code all of this in Python, but I retain a foundational understanding of most programming languages.

I recently trained in web and mobile application development. I use React and React Native for the frontend with JavaScript, and for the backend, I primarily use Django in Python. I am therefore capable of creating such applications, with a predefined design that I can replicate.

    Analysis of the customer database and sales of an alcohol sales company during 2022.
    Analysis of customer subgroups, product subgroups, and production of graphs interpretable by sales representatives.

    This taught me to adapt to client needs to properly present results, according to their expectations.

    October 2022 - May 2023 (7 months)
    I developed a Deep Learning algorithm to detect heart disease based on cardiac ultrasounds (videos).
    The main challenges were in processing the data, which was not very clean and also needed to be anonymized.
    This work was carried out in partnership with APHP, and the algorithm's performance was well-received, leading to a continuation of this project with a testing phase in other hospitals.

    Data scientist
    May 2022 - July 2022 (2 months)
    Paris, France
    The objective was to create a model to analyze videos and detect and classify LSF (French Sign Language) signs.

    First, I developed an annotation application in Python for annotators to indicate the sign and the frames of the sign.
    Second, I trained various Deep Learning models, inspired by different papers. I then compared these models using several metrics.
    Finally, I deployed a Flask app so the client could test our models from their location with their own videos.
