Professor, Electrical & Computer Engineering

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).

I have lots of experience using Unix/Linux tools such as Lex/Flex (for generating code for lexical analysis using regular expressions) and Yacc/Bison (for generating code for parsing languages defined by context-free grammars).  These classic tools are so powerful, they are still used today, especially for teaching about programming languages, regular expressions, context free grammars, and generating code for compilters and interpreters.

I have been using the Arduino microcontroller and development platform since it was first introduced, and even before that using its predecessor called Wiring.  The Arduino continues to be popular for teaching and for people who like combining sensors, LEDs, servo motors, and a little bit of logic in just a few pages of code to make a fun project.  Recently, I have helped musicians and artists who got their project mostly working, and needed just a little help debugging their code.  If you need an expert to take your Arduino project to the next level, ... let me know.

deep expertise with C language, transitioning to Go language, with focus on concurrency and throughput
