Data Scientist

Remote work, Russia · $1500 · 3 years of experience · Intermediate

I've finished additional courses Machine Learning, in Python and Scala for Data Science. I have skills in building data-scientific models in different areas: data-mining, forecasting, natural language understanding, and others. Also, I have knowledge in Deep Learning and widely useable frameworks for neural networks like Keras, Tensorflow, Pytorch. I can implement different models using: - linear and logistic regression; - neural networks; - support vector machines; - k-means clustering; - anomaly detection; - collaborative filtering to build a recommender system for movies. I'm also familiar with such techs as Jira and Confluence. I'm looking for for a job in ML or Data Science/Data Engineering field.

Python, Machine Learning, Data Science, Jupyter Notebook, scikit-learn, Keras, Tensorflow, Pandas, NumPy, Excel, Tableau, Deep Learning, NLP, Unix, Linux, Git, Math, Algorithms, Confluence, Jira, Kaffka, Hive, SQL

I consider offers from only English speaking companies.
