Hi, I'm Tim Harris

I'm a graduate student studying computer science and data science.

I use data to find insights, make business decisions, make predictions, and tell stories.

See below to see what I'm working on and to learn more about me.

Projects

Heart Disease Classification Machine Learning Model

Machine learning classification model that uses patient data to predict whether a patient has heart disease. Used logistic regression, k-nearest-neighbor, and random forest classification algorithms to predict if a patient has heart disease based on data such as age, sex, type of chest pain, resting blood pressure, cholestoral, fasting blood sugar, resting ecg results, and maximum heart rate.

Hockey Stats Data Scraper

Python code written to take data from hockey-reference.com that can be used for a machine learning model or a visualization dashboard.

University Library Book Recommendation System Database

Created a full relational database using MySQL Workbench that could be used by a university library. Designed and created a full relational database that would also allow users to review each book so that students and teachers could find the best books and textbooks for each subject.

Python RFM Analysis

Used python to determine how recently customers have shopped, how frequently they shop and how much they spend. I then classified customers based on those results.

Hockey Prediction Machine Learning Model

Used linear regression and random forest machine learning algorithms to predict the results of NHL hockey games based on data from previous games.

I am currently working on this project.

Asthma Patient Regression Model

Cleaned and transformed data for 99 asthma patients. Used clustering algorithms to try to create groups of patients. Created a random forest regression model to predict the severity of asthma symptoms for each patient based on the previous week’s data.

Book Tracker

Used Java and Spring Boot to create a web app to track books that I own, have read, and want to read. Used Cassandra for database management.

I am currently working on this project.

Interactive Data Visualization Dashboards

Student Loan Debt

Shows the amount of student loan debt in the US over time. One graph shows the amount held by different age groups over time, one shows the amount of debt held by groups with certain amounts of debt over time, one shows the amount of debt held in each state, and the last one shows how much debt is owed grouped by the amount of debt of borrowers.

NHL Player Nationalities

Shows where NHL hockey players are from, broken down by provinces and states for Canada and the US. I could not find a good visualization of that data, so I took data from hockey-reference.com and built one myself.

Covid-19 Cases, Hospitalizations, and Deaths

Shows the number of Covid-19 cases, hospitalizations, and deaths in King County, Washington by vaccination status over time. Also shows the sum of positive cases divided by the population of each group with a particular vaccination status over time.

Sales Report

A simple interactive sales report created with data from kaggle, similar to ones I have made for work.

Gas Prices

Shows gas prices plotted vs. inflation and vs. the profits of prominent gas and oil companies.Examines gas prices in Seattle and shows how the rise and fall of prices correlated with the inflation index and with how much profit the gas and oil companies were making.

Public School Teacher Salaries

Shows public school teacher salary figures by years of experience. Also shows amount of education and years of experience for teachers.

More About Me

I enjoy using tools such as Python, SQL, Power BI, and Excel to work with data to discover insights and patterns that can be used to tell a story, make predictions, or make business decisions. I am interested in roles where I can continue to learn new skills and continue working with data.

Originally, I got a degree in physics from University of Washington and was interested in civil and aerospace engineering, but during my senior year, while working as a data analyst for the Applied Physics Lab at UW, I discovered that coding and working with data was what I wanted to focus on in my career.

After graduating, I decided to go back to school to get a graduate certificate in computer science fundamentals from Seattle University. There, I learned how to write code in Java and C++. I also learned about data structures, algorithms, and how to use database systems with SQL.

Now I am working on my masters in computer science specializing in data science.

I am a big fan of hockey and football and my hobbies include reading, camping, hiking, and cooking.
