Experience

Procedural Terrain Generation Tool (Development)
https://github.com/tferega/terra-gen
This tool generates terrain height-maps using a variety of algorithms. Currently implemented algorithms are random noise, diamond-square, voronoi diagrams, and probability function. They can be mixed and matched as needed.
Process Runner (Development)
https://github.com/tferega/process-runner
A simple Scala library that greatly simplifies certain use-cases of native process running.
Selenate (Development)
https://github.com/tferega/selenate
This is a mini-framework I created that is built on top of Selenium. Selenate decouples Firefox sessions from client code, facilitating management. The server-side is written in Scala with Akka. The client-side is written in Java.
Scala SSL Disabler (Other amazing things)
