On September 13, on the Day of the Programmer, CactusSoft developers organized a Meetup dedicated to high-tech topics – artificial intelligence and blockchain development.
Nikita Krylov, a Machine Learning Engineer and recent bronze winner in a competition run by Google, opened the Meetup with a speech about machine learning. He told the audience about his move into ML, explained how to start a career as a Machine Learning engineer and showed them how to take part in competitions on kaggle.com (a platform for carrying out data science projects).
