I was working as Python developer for 1 year. I've been developing telegram bots. I've been a school student of RR ML school for the last three months.During that time, we've been teaching the entire machine learning flow. As a result, I develop a machine learning system to predict the price of an apartment. We took the data from domria. And the final system will contain api, an algorithm that learned not only on ordinary features but also on vector representation of pictures, descriptions, etc. I used: pytorch, cnn, MLP, gradient bosting, numpy, pandas, scrapy, postgrec, scikit-learn, pickle, flask etc.
