Operating systems (kernels, file system code),
system architecture,
language design,
compilers and related tools,
networking in a hostile environment (such as the Internet),

and technical writing and editing.
Experience (PDF, Word/DOC) includes substantially improving productivity of software developers, testers, technical writers and editors, system administrators, and end users, via thoughtful analysis of workload, process, and quality controls, followed up with research, proposal, development, implementation, and maintenance of optimizations.

Projects |
Researching email abuse and developing practical countermeasures, as a
benefit to those who make legitimate use of the Internet without abusing
its inherently cooperative nature.
Serving as "postmaster" for my own domain names,
rather than outsourcing that work, mainly to increase my own understanding
of the challenges of doing so.
Previous projects include porting and subsequently optimizing a native-code generator for the Verilog language, targeting the SPARCv8 architecture, originally targeting HP-PA RISC; GNU FORTRAN 77, which I wrote and maintained over a period of many years; and design, reverse-engineering, and documentation for a page-layout-software company.

Spam, Viruses, Etc. |
I don't send spam, viruses, etc.,
though such material often "pretends" to come from me or one of
the domain names I control.
Email header lines such as "From:", "Reply-To:", and "Return-Path:" can be easily forged by a sender, as can "Received:" in certain cases. Don't trust them!

Contact |
Feel free to contact me by emailing james-availability at jcb-sc.com
about my availability to work on your project.
Important: If you're using anti-spam measures such as RBLs listing dynamic IP blocks, you might not hear back from me, as my emails to you might be blocked. Either whitelist me, or tell me how else to reach you — even a specific IP address and/or (SMTP) port number I can use to deliver email to you, which you've set up to receive email without such blocking in place, would do just fine. I do now publish SPF records, though I don't recommend reliance on their use. My GPG/PGP public key is available.
