http://asksasha.com/Specializing in MySQL source code customization and MySQL database optimization. This is an area of particular strength because I have worked for 3 years for MySQL, wrote the replication code, and did a lot of bug fixing and random features in other areas of the code. I also worked as a support engineer at that time, and have written two books - MySQL Enterprise Solutions and Understanding MySQL Internals.
Can do other things that many others can do as well - PHP/C/C++/Perl/Python programming, web application development, Unix/Linux system administration, and can generally resolve a difficult computer-related issue quicker than the average Joe.
