ABOUT ME

Senior Performance Developer at NuData Security

Having sold my first program after teaching myself assembler at age eleven, I have over 35,000 hours of hands-on experience architecting & developing software including expertise in leading software development teams from concept to completion. I typically work on cutting edge software technology regarding problems considered to be impossible or too difficult for most developers, or where performance is critical and will e.g. reduce the cost of doing business or enable other technology. I ultimately provide a unique business advantage by thinking out of the box.

Specialties: High performance (high tens of thousands of network transactions per second per core), massively scalable (tens of millions of peers), robust (weathers DDOS, never swaps RAM), real time systems, C / embedded C89 / Perl, multi- host / process / threading / event-based, TCP/IP & UDP & derivative protocols, Cross-platform (Unix / FreeBSD / Solaris / Win32), Algorithms; search / hashing / compression, Software architecture / development process; quality assurance through disciplined excellence.
