Data Scientist

Remote work, United States · $2000 · Advanced/Fluent

I am an English native speaker, looking for work in a collaborative professional environment with room to develop. I am currently pursuing a master's degree in data analytics and have academic experience building classification and regression machine learning models and utilizing a variety of data science algorithms. Some of my completed projects are a model for predicting whether a flight will have empty seats using pandas and PySpark and I am currently working on training a model for article classification. Furthermore, I have a bachelor's degree in mathematics which allows deep understanding of the underpinnings of data science.

Python, Machine Learning, Data Science, SQL, Math, pandas, Jupyter Notebook, NumPy, Algorithms, English, Pandas, Tableau, Statistics, Excel, Bayesian Inference, Unsupervised Learning, R Language, Communication Skills, Agile, MySQL

I am proud to have a bachelor's in mathematics from an American university which I believe showcases and helped to develop a strong capacity for understanding logical structures, such as those found in data science. I am also particularly proud of a project where I was tasked with creating visualizations of a data tree model to predict customer purchase trends.

I would like to work in a supportive environment with room for collaboration and development. I would prefer to work in an Agile team. As someone who is pre-intermediate in Russian, I would benefit from working in an environment with many colleagues who can speak English.

Data Analyst

Remote work, Ukraine · $1800 · 5 years of experience · Upper Intermediate

Five years as data analyst in total. Last three years I’ve been working in IT product analytics, where I’ve closed countless number of analytical tasks in user acquisition, payments, ad monetization and CRM, mostly answering the question: “how can we increase revenue?”. Last year I’ve been focused primarily on user behavior on the product, aiming to reveal casual relationships between sequences of user actions on particular lifetime and churn / revenue.

Python, SQL, Tableau

- Developed user scoring model for irrelevant \ motivated traffic detection on low amounts of user acquisition - Derived heuristic rules for 'whales' churn prediction - Automatized target KPIs downturns analysis - Actually, helped that guy who asked for help with excel formula

Dos: - product company - bureaucracy free environment - peers focused on solving product problem rather than applying specific ML tool Don'ts: - "excel" in required skills
