Jan 2021 - Dec 2022
Argentina I defined development priorities for my team alongside Tech and Product managers. I coor- dinated the migration from in-house GLMs estimators to LightGBM. We professionalized the team, by implementing agile methodologies, documenting internal libraries and setting reproducibility standards for our analysis. I wrote the first career ladder, updated the technical exams and grew the team from 7 to 12 people.

Argentina I assisted in the development of the income optimization engine for our Real Time Bidding (RTB) service. We presented the results in the 2019 KDD. Our team was responsible for the system predicting ads’ conversion rates (win rate, CTR, CVR). We trained cheaply on several billions observations with an in-house, online SGD algo, and processed 1M+ auctions per seconds, using strongly regularised GLMs.
