PocketPatch is a Ruby on Rails web application for personal finance management. It allows users to connect their bank accounts through Plaid and classifies their expenses automatically using a machine learning (ML) model.

I built both the main Ruby on Rails application that interfaces with Plaid and serves the UI and a small service that hosts the ML models (ClassyMoney).

A compilation of Ruby on Rails example apps that showcase small problems I've had to solve with Rails. I hope to grow it over time and eventually add more detailed explanations through a blog. So far, I have published three repositories and have code for the other three examples that I still need to clean up.

I built, for personal use, this simple calendar with a to-do list, a day planner, and a habit tracker using Ruby on Rails. It was mostly an experiment for using Hotwire and the latest tooling for Rails front-end interactions but I'm still working on improving it.

A small Flask-based service to categorize (classify) financial transactions according to a user's previous categorization. It provides an endpoint to fit a machine learning model and one to make predictions with it. It complements PocketPatch.
