I am an expert Matlab programmer. I have won prizes in Matlab Contests. I have a PhD in Computer Science from Stanford. I have used Matlab for computational modelling, statistical analysis, experimental data analysis.

I have developed web applications using PHP in a LAMP environment (Linux, Apache, MySQL, PHP), including things like web telephony (Twilio) and specialized web services for affilate marketing.

I have developed databases using MySQL for use with web applications in a LAMP environment (Linux, Apache, MySQL, PHP).

I am an experienced Linux admin for supporting web applications in a LAMP environment (Linux, Apache, MySQL, PHP), and in particular using Ubuntu Linux.

I have been an expert in C programming for a very long time. I have designed and implemented many sophisticated algorithms in C. I have a PhD in Computer Science from Stanford University.

I recently provided a solution in Ada to a happy client. Who knew there would still be interest in this classic programming language! Despite many years since I had written any code in Ada, it still feels very familar, perhaps because of its similarity to Pascal. If you have any programming problems in Ada, let me know!

I worked in a university microprocessor lab and I've done quite a bit of low-level assembly language programming on a variety of architectures, including the PDP 11/70 (on which C & Unix were developed), the 8080 and Z80 that powered early CP/M computers, the 6502 that powered the Apple II, and various Motorola CPUs, like the M6809 and M68k. I remember when RISC architectures were new, including SPARC and MIPS, and these still seem to be used in teaching. Of course, I am familiar with the Intel x86 architecture, so I have been able to help a few students who wanted to understand how to exploit a buffer overflow vulnerability in a C program to overwrite the stack frame (and execute a root shell).
