Paul Andrews’s Summary

I have worked in the software industry since graduating from Cambridge in 1982. From 1990 to 2000 I worked as an independent consultant - initially as a C++ developer and later as a Systems Architect - for major investment banks.

During this time I have gained much experience in defining and implementing large scale distributed software systems for my client companies.

My work includes: Guiding implementation teams through technology choices. Ensuring that issues such as scale, performance, availability and risk are addressed at all stages of a project. Providing hands-on development expertise as appropriate. Assessing existing architectures. Liaising with exernal and internal groups and individuals.

Paul Andrews’s Interests:

I am a project administrator for Lejos (http://sourceforge.net/projects/lejos/), an open-source Java VM for the Lego Robotics Invention System. The VM, written in C, runs in 32K of RAM and implements almost all of the Java language apart from garbage collection. I wrote the real-time scheduler, the thread monitor functions and the heap manager. I also wrote various Java robotics classes, modified some of the fundamental math routines and enhanced the firmware comms stack. This brings together my interests in OO, robotics and machine intelligence.
