Work Experience

Senior Data Scientist

2019 - 2022
  • Directed the continuous improvement of a receipt-processing API that extracts essential information from images. Reduced response time and memory footprint by 75% and improved accuracy.
  • Developed deep-learning computer vision algorithms for document processing in TensorFlow, such as OCR, segmentation, and classification.
  • Designed synthetic data generators to train these models without manually labeled data.
  • Created a cleaning tool to improve data quality automatically.
Technologies: Python 3, TensorFlow

Data Scientist

2017 - 2019
Orange Bank
  • Managed a team of two data scientists for a fraud detection task. Tested, supervised (XGBoost), and unsupervised (auto-encoders) algorithms with financial analysts and achieved a recall of 85%.
  • Developed NLP algorithms to improve conversational frameworks like Rasa and Watson, including sentiment analysis, entity extraction, and intent classification.
  • Aggregated and cleaned online posts from various sources, such as Twitter, Facebook, app stores, and blogs, to prepare training corpora adapted to the mobile banking industry.
  • Designed a social media post analysis tool for the marketing team.

IT Consultant

2014 - 2015
Mazars USA
  • Developed a fraud-detection system using machine learning.
  • Completed IT general-control audits, including security review, risk assessment, and automation of these processes.
  • Performed consulting technology missions, such as data mining and penetration testing in the energy and financial sectors.
Technologies: Fraud Audits, Anomaly Detection, Know Your Customer (KYC), Python 3, Excel VBA

Twitter Dashboard | French 2017 Elections
Developed a microservice-based app to track the evolution of topics and sentiments mentioned on Twitter during the 2017 French presidential elections. The topic modeling was updated daily based on the latest trends.

Discrete Simulation Monte Carlo

Developed a new method for the US Air Force to model fluid flow in a very low-pressure environment. I wrote a model to simulate a Couette flow between two plates in Fortran 90. Established an explicit coupling between the direct simulation Monte Carlo and the Navier-Stokes equation.
