🤖 I use analytics, machine learning and deep learning to fight spam content at work. Classic ML algorithms, time series analysis, natural language processing, or computer vision are just some examples of the techniques I’ve used.

🧑‍🏭 I like learning and teaching things! I'm a chemical engineer turned data scientist. I self-learnt pretty much everything to move into tech. I'm now pursuing my Master's in Computer Science, teaching at a data science bootcamp, and sharing data science knowledge online.
