Almost 5 years of experience as a senior data analyst at Wayfair in Berlin. Eager to expand skills in the data fields. 10 years of experience as a freelance copywriter (since 2009). 5 years working remotely in Comparic Group - major website in Poland educating and informing about financial markets (2014-19). MBA in business analytics – 5 years of strong foundations in data science and machine learning (2011-16). Knowledge of Python, Pandas, SQL, Matplotlib, NumPy, Spark, Git.

Here are my Python projects:

• Are new movies longer than they were 10, 20, 50 years ago? – I’m a big fan of movies. Some time ago I wondered if movies nowadays are longer or I just feel this way. To examine this issue, I used IMDb data and did exploratory analysis using Python with Pandas, Matplotlib and Seaborn. The chart I created received 3.6k upvotes on Reddit’s Data is Beautiful. The article about my working process and results was published on Towards Data Science.
• Dot Plot in Python – Every year I prepare analysis of Oscar nominated movies and publish it on my Facebook wall. In 2019 I wanted to attach something interesting – a dot plot with all movies I’ve seen and rated in my life. Quickly I figured out that there is no plot I need in Matplotlib and Seaborn libraries. I decided to modify classic scatterplot to meet my needs. This project shows that I can create new tools if needed. The tutorial about creating dot plots was also published on Towards Data Science.
• Bokeh Trade Balance – Interactive charts are appealing to the audience, especially people without experience with statistics and data science. This project is a result of my experiments with Bokeh library. I used Trade Balance data from Poland to show how both import and export grew few times since joining EU back in 2004.
• Medical Appointment No-Show – In this project I took the data about medical appointments in Vitoria (Brazil) and tried to predict whether patients will show up for their visit in the hospital. I used a variety of models to get the best results, from logistic regression to random forests and support vector machines.
