Feb 2023 - Apr 2023
I shared my expertise in big data, machine learning, and related technologies with Master students. In my lectures, I offered an in-depth exploration of the industry, discussing various roles, collaboration dynamics, experience levels, and tools used. I highlighted the latest advancements in NLP, particularly LLMs (Large Language Models). I delved into the inner workings of Transformers-based models, specifically GPT and chatGPT, and their attention mechanism. I also explored the promising future of AI in this domain, considering potential breakthroughs and associated risks. I provided hands-on guidance and assistance for their machine learning projects, involving computer vision and NLP models. Show less

Data Scientist II

Sep 2020 - Sep 2022
Only data scientist in Amazon's EU Pricing team (10 people total, product managers and BIEs)• Spearheading efforts to reduce price volatility, resulting in a 25% decrease within the first year. I leveraged my expertise in statistical methods and distributed architecture to analyze price changes of 100M+ products over a 5-year period, identifying key drivers of volatility and working closely with stakeholders across the US and EU to develop and test strategies to mitigate its impact on profitability. These programs involved cross-functional collaboration with teams in customer support, category management, software engineering, and more.• Designing and executing A/B tests to estimate the financial impact of price strategy changes, leading to more informed pricing decisions and the avoidance of multiple programs that were initially thought to be profitable but turned out to be money-wasters. It also allowed highly profitable projects relative to competitor monitoring, pricing strategies designed in the absence of competitors, and abusive customer returns, among others, to get pushed above the line.• Working with science teams on a bayesian model of price elasticity, providing business teams worldwide with accurate estimates (and uncertainty) of the financial impact of pricing decisions and helping senior leaders replace emotional debates by data driven decision making.
