I was a member of the National Honor Society (NHS) in high school. In college, I was a member of the honors fraternity, Alpha Lambda Delta. I have done volunteer work at the Howard County Library and participated in volunteer work and other activities with the service fraternity, Alpha Phi Omega. Recently, I have been volunteering at Habitat for Humanity.

Experience:

Among jobs, internships, and graduate student experience, I have about 4 years of work experience. I have written code in the following languages: C, C++, Qbasic, Java, Python, Ruby, SQL, Matlab, Maple, Elisp, Scheme, Pascal, Tcl, Ocaml, Verilog, some shells, and a number of assembly languages. About three or four are used regularly. I've written software on the order of 10s of lines, 100s of lines, and 1000s of lines of code. (In case you're of the KLOC persuasion, keep in mind, writing a few hundred lines of numerical code is difficult. Implementing a few-hundred line, complicated numerical algorithm that runs in real-time and is optimized for a given architecture is orders of magnitude more difficult than writing a few hundred lines of code in Python to parse some XML.) I'm familiar with some of the Matlab tool boxes. I've implemented some of functions myself and could probably implement many more with less than a week of research. I've also done a few projects involving audio and image compression. (Terms like ADPCM, LPC, Vector Quantization, Discrete Fourier/Cosine/Wavelet Transform are all familiar to me.)

Ideal Job:

After being asked this a number of times, I've thought about it and decided to get it in writing. Ideally, I'd like to be learning, implementing, testing, tweaking new algorithms. It can be simulation or real time (if that's appropriate). It will probably involve signal processing, communications, image processing, or non-numerical algorithms. There will probably be at least some level of math involved. I like working in Matlab. I also like architecting software. This should give you a decent idea.
