About Antoine

Senior Quant Analyst & Data Scientist, specializing in time series, stochastic modeling, and industrializing Python models in production.

What characterizes me: I don't deliver a notebook, I deliver code that runs. Clean modeling, rigorous back-tests, tests, documentation, monitoring. Too many brilliant models die in prototype due to lack of industrialization, which is precisely where I bring the most value.
