About my work

I started as Financial Analyst and has grown to CFO.
Then I changed my job field into psychology, where I created my own business and developed several psychological games.
Now I work as a data analyst, developing web applications using artificial intelligence and machine learning. I realized that it is extremely important to count in human factor: the key to perfecting data patterns is merging technical and cognitive ergonomics. Great data analysis is data storytelling that will allow to present key points to stakeholders in the most precized way.
While I'm specializing in statistical modeling and forecasting, I utilize my AWS, RDS, S3 and other cloud-native tools to provide informative data and support functionality to the product.

Technologies I use:

Tableau, VBA/Excel, API, Bootstrap, MongoDB, R,
Python, JavaScript, SQL, HTML5/CSS

Using Tableau to visualize bike-sharing data CitiBike

CitiBike

I used Citi Bike data that has been released to the public for my analysis and used Tableau to visualize bike-sharing data. I found out which data could be apply to Des Moines, drawing on both the data expertise and my critical thinking skills. To solidify the proposal, I created the detailed bike trip analysis.

Originally data was stored in the csv file, I used Pandas to change the "tripduration" column from an integer to a datetime datatype, and Tableau to vizualize the analysis.

This microorganism can supply next best taste of food, and apparently lives in a human belly button. The company needs volunteers who will take participation in the research: between individuals quantity of bacterial species may vary even in the same location.
By toggling the ID number in the drop-down menu you can discover demographic info each particular participant, what bacteria they contain, how often they participated in the belly buttons washing, and the bubble chart of all bacteria cultures in their sample.
