Li Zhang's Portfolio

Highly motivated Master student building a career in the field of Data Analysis. Curious about learning new programming languages and so far have excelled Python, R, SQL and Java. Skilled in Communication, Leadership, Adaptability, Perception and Team Work.
Passionate about Pure Mathematics researchs (Point-Set Topology and Harmonic analysis)).

Covid 19 Data Exploration

In the project we using Excel and MySQL to perform Data Cleaning, Data Exploration and merge datasets to caculate nedded measures and contruct new datasets prepare for future analysis.
Then utillized Tableau to create several dashboards to produce visualization of the data based on datasets created determine the correlation between covid effects and various life factors and effect of vaccination.

R Shiny TTC Subway Delay Forecasting App

In this project we will build an R Shiny web app to predict the TTC subway delay information using the forecasting methods like ARIMA model, ETS, STL and Tbats.
Where delay information about each lines is in time series variables format and create a selector/drop down for which data set to choose along with a a slider bar for the number of forecasts to produce

Data Cleaning in SQL

In this project we take raw housing data and transform it in MySQL change the format and delete missing and duplicate data to make it more usable for analysis.

Amazon Web Scrabpping Project

In this project we inspect the website HTML source prasing and explore the structure of the website using Beautiful soup library create function automate downloading and parsing the information saving as CSV, and send notification email when price change.

Python Movie correlation Project

In this project we utillized Python to perform Data cleaning by change data format and filtering out data, look at both numeric and non numeric data determine which factor is more correlated with gross revenue than other.

Group in Topology

In this research we explore the elementary ideas of simplificial complexes, boundary and homology theory that all together lead to homology groups.
