Data Analyst and PhD Student in Computer Science

I'm a freelance machine learning, deep learning, and data science specialist with 5 years experience developing data science products and predictive models in multiple fields including healthcare, retail, utilities infrastructure, and academic research. I also have experience working with cloud computing infrastructure for data processing In 2017 I won the first place on the CrowdANALYTIX Identifying Themes from Mobile Case Images image classification contest! (More details below in the portfolio) I prefer to work on long-term and hourly projects, but I'm open to working on interesting projects of all sizes. Also, I love to work on scientific projects, and I can give you a discount if you are a graduate student with a limited budget needing help with your thesis or paper, as I have experience in the academia: I have taught an introductory graduate course on machine learning, and advised and collaborated on several theses on data analysis.
