About Me

Hi, I’m Ronnie Hill! After spending 15 years in sales, I decided to transition into data science. I’m currently working toward my Master’s degree, set to graduate in Spring 2025. While attending school I have earned certifications in Google Data Analytics and Cloudera Big Data with SQL. I’m passionate about transforming data into actionable insights and love the problem-solving challenges this field offers. Outside of work, I enjoy spending time with my wife and kids, camping, and playing board games. Always eager to learn, I’m excited to apply my skills in SQL, Python, and machine learning to make a meaningful impact in data science.

Projects

  • Consumer Sales Analysis with SQL: Created a customer_spending table in PostgreSQL, Developed and executed multiple SQL queries to extract insights such as: Total Revenue by category, demographic analysis, average unit price and costs, etc..
  • Mushroom Classification Using Machine Learning: Developed a machine learning model to predict edibility of mushrooms (edible or poisonous). Split data into training and test subsets, applied one-hot and label encoding, constructed a 2 layer neural network for predicting edibility, created a confusion matrix to represent how well my model was predicting, last but not least created extensive documentation to clarify work and allow for reproducibility.
  • Credit Card Fraud Detection Projects: Implemented PCA for dimensionality reduction in credit card transaction datasets to identify anomalies, comparing results with the original data. Developed and trained a neural network for classifying fraudulent transactions, achieving enhanced detection rates, and utilized a Confusion Matrix to present findings.
