-  The last project I created at Avaak is a system monitoring tool which spoofed
-  Avaak's clients to test their servers.  This project weighed in at 3kloc of
-  Ruby.  I also created a test framework for the firmware on the router product
-  which cross-compiled unit tests, loaded the binary onto the target hardware,
-  ran the tests and reported results.  An earlier project had invariant image
-  feature extraction in C.  Later, I used PCA, and Fischerfaces analysis under
-  the supervision of Serge Belongie, Ph.D. UCSD.  My first project was a
-  firmware loader for an embedded camera hardware using mspgcc and C.
+  $\cdot{}$ Avaak Inc. cameras that communicate wirelessly to a base station.
+  The base station also communicated back to central servers.  Under heavy load,
+  communication would break down.  They needed a way to generate such loads and
+  log the communications and asked me to simulate the cameras and the base
+  station.  I set out simulating the camera first since it only communicated
+  with a base station and I could have a real one at my desk during
+  development.  Also once it was developed it would make developing the base
+  station easier.  All of this went according to plan, but communication between
+  the base station and the central server was much more difficult than
+  anticipated.  The central server had bad logging facilities and it was not
+  feasible to modify it.  To work around this, I developed a server that could
+  run locally to facilitate the base station's server communication development.
+  The simulators worked well and logged in a very readable format all
+  camera, base station and server communications.  Hundreds of simulated
+  cameras revealed that the central server's memory was maxed out with a high
+  number of connections.
+  \newline{}
+  $\cdot{}$ After using the simulator to diagnose problems like the central
+  server's memory maxing out, Avaak wanted to use the tool to monitor the
+  health of the system.  This was a relatively easy addition that just needed
+  simulate a round trip of a picture taken on a camera and then being visible
+  on the website.  This system emails logs of minor problems and sends a text
+  in addition to a more detailed email for major problem.  On catastrophic
+  failures, I included myself on the emails.  Several months after I left I
+  received emails from this tool, so I knew it was still doing its job.  At the
+  end of my work on this project, it weighed in at 3kloc of ruby.
+  \newline{}
+  $\cdot{}$ Mike Sailor's chem lab at UCSD developed reusable chemical sensors.
+  They enlisted the help of Avaak to figure characterize the sensor's changes
+  when an agent was introduced to the environment.  Working with Serge Belongie
+  and Clark Guest, computer vision experts at UCSD, I developed C and matlab
+  classifiers.  These classifiers generated data which we analyzed using
+  invariants, and later PCA, and Fischerfaces.  The conclusion of this analyses
+  was used to justify further research by Mike Sailor and his lab into their
+  reusable chemical sensors.
