🙋‍♂️ Introducing Myself

Hello! I'm Rich, a data analyst with a background in data product management and software development.

This portolio page is where I track my personal development and showcase what I've been working on.

🌱 Portfolio Projects

Social Network Customer Churn Analysis and Prediction

A project demonstrating techniques for understanding and predicting customer churn for a simulated social network. By combining product usage analytics event data with customer subscription data, we can reveal which usage behaviours have the biggest impact on churn probability and predict the churn probability of individual accounts.

Sakila Film Streaming: Transforming Streaming Data for Analytics

Uses AWS components to combine a SQL database with streaming event data and transform it for analysis with Amazon Athena.

Data Engineering | Kinesis Firehose | S3 | AWS Glue | AWS Lambda

Dessert or Not? - A PySpark Logistic Regression Pipeline

A data cleaning and logistic regression pipeline implemented in PySpark which examines which aspects of an Epicurious recipe are important in determining whether or not the recipe is for a dessert. The final pyspark.ml Pipeline uses custom-made Transformers and Estimators for missing value imputation and outlier capping.
