My name is Alex Gartrell and I'm a Software Engineer at Facebook, where I work on the Content Distribution Network as a member of the Traffic Infrastructure team. At Facebook, I've worked on flash-based caches, HTTP load balancers, a new protocol for memcache operations, and various other C and C++ systems.
I graduated with a major in Computer Science and minor in Software Engineering from Carnegie Mellon University in Pittsburgh, PA. While there, I TAed 15-213 Introduction to Computer Systems and 15-313 Fundamentals of Software Engineering. I did a senior thesis where I wrote a linux kernel extension for thrift message routing.
In the past I contributed to Mongrel2. I worked on static file serving (default files, metadata caching, etc.) and I added SSL support using an embeddable SSL library, PolarSSL. I believe I still have commit access, but do not consider myself (and should not be considered by you to be) an active contributer.
While in school I took a Software Engineering class where we were to work on a large project. My groupmate and I chose to work on Chromium. I landed a couple patches involving Chromium's sync functionality, but nothing major.
