I also led a team that re-implemented the integration between the customer-facing site and the reservation management back-end utilized by restaurants using a service-oriented architecture.
ControlTower is an HTTP application server for MacRuby. As a member of the OS X Server team at Apple, I developed ControlTower to meet the needs of a larger project, as there were no existing application servers at the time that worked with MacRuby and met all of the project requirements.
Evolver is a "toy simulation" of an evolutionary system that I implemented as part of my doctoral thesis research in the field of evolutionary biology. Utilizing Ruby, it allows for all of the important parameters of the simulation to be specified via configuration file, while still running fast enough to complete simulations in a reasonable amount of time.
In the process of studying both Objective-C and the various fixed-point combinators from the lambda calculus, I conceived of a way to utilize Objective-C's blocks to implement the Y-combinator. This is more of a fun, exploratory project than something intended for production use (though there's no reason it shouldn't work in a production system).
