About Quentin

Graduated as an engineer from ISAE Supaero in 2017, I started my career at Telespazio France as a Data Scientist specializing in Computer Vision and geo-information. I developed deep learning algorithms for satellite image processing while setting up big data infrastructures with PostgreSQL, Hadoop, and PySpark.

In 2019, I co-founded FDTI Consulting where I led data science projects from A to Z, from client acquisition to delivery. This entrepreneurial experience allowed me to acquire a global vision of the business and develop my skills in project management and client relations.

From 2021 to 2023, I joined Microsoft in Italy to work on the automatic detection of manufacturing defects. I designed and deployed Computer Vision models in production, focusing on the quality of datasets and the establishment of sustainable ML infrastructures. During this period, I also experienced digital nomadism in Europe, working from a converted van.

In 2023, I joined Crédit Agricole in Portugal as a Data Engineer to standardize ETL procedures and set up CI/CD pipelines. An enriching experience in the financial sector that confronted me with the challenges of critical data in real-time.
Since 2025, I have been developing Kreatube, my own platform for assisting in the creation of YouTube content, using React, Node.js, Python, and the integration of LLM APIs. A project that combines my technical skills and my passion for product innovation.

    April 2021 - February 2023 (1 year and 10 months)
    Milan, Italy
    Development and implementation of deep learning algorithms enabling the automatic visual detection of anomalies, on production lines in the luxury industry.

    The main challenges were:
    - Supporting the client in creating a clean dataset, conducive to training machine learning models;
    - Setting up an infrastructure to perform deep learning on such large datasets (the final dataset contained several tens of thousands of high-quality images);
    - Popularizing the operation of complex deep learning models to establish the client's confidence in the robustness of the results;
    - Implementing the final model on the client's production line, and ensuring its monitoring over time thanks to MLOps pipelines on Azure.

    Tools used: mainly Python, Azure expert, data visualization (PowerBI, Streamlit), containerization (Docker, Kubernetes), DevOps best practices, implementation and use of MLOps pipelines.

    Computer Vision algorithms implemented (under Pytorch): FasterRCNN, DETR, EfficientDet, YOLO, Autoencoders, Siamese Networks, GAN
