===High-level programming===

Probably the most complicated programming project I have worked on was one where we were attempting to predict how two proteins will interact. Since billions of calculations (a minimum of 2.7 x 10^10) are needed for each protein/protein complex, I had to write specific (C) code that was optimised to run in parallel on a dedicated cluster of 256 CPUs (using the MPICH compiler). As a side note, I had to translate some original Fortran77 code into C so it could be compiled with MPICC.

We wanted to make our algorithm available to the general scientific community and, so, we decided that a web server would be the best implementation. What we needed was a simple, user-friendly interface to the back-end algorithm. Getting the user input (here the coordinates for each atom in a protein) to be transferred to the cluster required a great deal of pre-processing (data parsing, formatting, and error-checking). Likewise, the results returned by the cluster required post-processing to be eventually sent (via email) to the user.

The entire system had to run autonomously (controlled via crontab scheduling). As the administrator of this setup, I was responsible for keeping the system up at all times. However, since there were thousands of lines of code, if the system should crash it would be difficult to find out where the problem was if I didn't maintain extensive log files. I set these up to be easily parsable and had the system periodically email me the "health" of the system. This server remains up-and-running to this day.

===Data mining / data parsing / data manipulation===

The algorithm described above is implemented through a combination of Fortran77 and C code. However, the initial data (input) and results (output) are sent through multiple pipes as a series of I/O streams using Perl, awk/gawk, sed, and bash scripts. They are all controlled via makefiles and use extensive regular expressions.

I would say that working with the command line interface (CLI) and scripting languages are my main skills and strengths. These skills have been developed through over seven years of active data mining through literally hundreds of terabytes of data in a wide array of formats and from multiple sources.

===Database experience===
A different project I worked on also required extensive data mining. However, here we were more interested in storing our data in easily manageable (MySQL) databases. On this particular project, we were working with the human genome. Each genome has over three billion "letters" (or bits of information). However, after adding annotation we were dealing with tens of gigabytes of data for each genome and for each experiment. After completing a couple of these experiments, we were quickly dealing with nearly 100 gigabytes of data. This required extensive data normalization and carefully constructed databases.
