Car Data

Car Data is an ETL pipeline that scrapes model information about cars directly from the websites of auto manufacturers. The information targeted is configuration options, such as interior colors, performance packages, wheel options, trim levels etc. Currently, 24,000 configuration options from 406 car models area accessible by this project.

Key challenges of the project were reverse engineering public APIs of car manufacturers to access the required data. Designing a flexible, but still useful data model, required a lot of thought and some compromise. A model was developed which preserved a maximum amount of information, while minimally destructuring the data.

NoDoze

If you have ever disabled sleep on your computer to allow a long-running task to complete, NoDoze might offer you a better solution. NoDoze is a daemon written in Python that delays sleep in response to conditions that you configure.

These conditions can be something like an app running or a server streaming a media file. A simple plugin interface and plugin autodiscovery make it possible to easily add new plugins. Additionally, a straightforward YAML configuration offers ways to tweak existing plugins.

This project gave me the opportunity to hack some pretty fundamental parts of Linux including D-Bus messaging and interprocess signaling using file descriptor locks.

DocuCloud

DocuCloud is a cloud file system that implements file versioning through copy-on-write. The project is similar in idea to Google drive. The greatest challenges in this project were focused around modeling a filesystem in a Postgres database. Handling distributed transactions across S3 and Postgres was another interesting challenge. The GitHub README goes into more detail, if you're curious.

Reactive Notes App

Reactive programming is more polarizing to the Java community than even the Eclipse vs IntelliJ debate! I wanted to judge reactive for myself.

This project allowed me to explore Project Reactor and Spring Webflux in a fun, yet relatively simple CRUD note making app. Beyond learning reactive, I really had to get my hands dirty with Spring Security, KeyCloak and OAuth2. I also put on my webdev hat and built a React SPA frontend.
