To contribute to a team of gifted, motivated problem solvers,
committed to excellence, as a systems architect,
integration specialist, software
developer, infrastructure architect,
toolsmith, or general
troubleshooter. To use and expand my skills, experience,
and knowledge, in the pursuit of personal and professional
growth and positive change.
As a general technologist, I've acquired an expansive body of
skills, experience, and knowledge of technologies,
methodologies, and problem domains. I've delved deeply into the
unique problems of, and principle technologies behind:
- Systems support and infrastructure for software development and deployment
- Digital Multimedia, graphic design and prepress
- Network design, deployment, and operations (including network security)
- Accounting (of assets, inventory, debts, transactions, and time)
- Content- and Asset-management for web-based publication
- Workflow and digital document management
- Premises security (i.e., alarms, locks, etc.)
Since my start in the industry in 1989, I've dedicated myself to
understanding problem domains, technologies, and the human
factors issues that bridge those two worlds. In the intervening
decade and a half of work, I've acquired a unique and thorough
blend of experiences with systems, solutions, and the business
problems to which the solutions apply.
I've been a software developer, systems and infrastructure
architect, and general technologist, de facto human factors
consultant, graphic designer, and support technician. I
understand technology from the lowest levels to the highest, and
am comfortable operating at any and all of those levels.
I have exceptional talents for:
- Analysis, pattern discovery, and synthesis
- System architecture
- Human and computer language (especially metaphor and analogy)
I have specific skills in, and passions for:
- Infrastructure software (i.e., software in support of other technological ends)
- Visual design and layout, in both traditional and electronic media
- Data mining, especially scrubbing and cleansing, and reverse-engineering
- Software frameworks (i.e., rationalizing code into libraries, toolsets, etc.)
- Bridging technology gaps (e.g., inter-language integration)
I list these in three groups. In the first group are those
languages in which I have achieved mastery and worked
“deep black magic.” I list them in reverse
chronological order of my initial experience with them (which
roughly approximates the order of my mastery and adoption of
each of them as my language of choice, although in several cases
there is significant overlap.)
- MC68HC11 Assembly
- Visual Basic
In the second group are those languages with which I have
achieved familiarity and the ability to accomplish functional
work, but have not had occasion or specific reason to explore in
more depth. I list these in reverse order of my skill level with
them (greatest to least.)
- Jython (Python implemented in Java)
- Emacs LISP / LISP / AutoLISP
In the third group are those languages with which I have a
conceptual familiarity and have written “toy”
programs to exercise concepts, but have not written significant
code, or even short, task-specific programs. I group these
(roughly) by language type:
- Self, CLOS, Prolog
- Z80 Assembly (have reverse-engineered from machine code)
These are purpose-specific languages which, even when
Turing-complete, are narrow in their scope. I group
these (roughly) by type and purpose, but the groups are
- Generalized Markup: SGML, XML, YAML
- Stylesheets and Layout: PostScript , CSS1, CSS2+Positioning, XSLT + XSL-FO
- Hypertext Markup and Layout: HTML, XHTML
- Document Markup: LATEX
- Text Search: Regular Expressions (POSIX, Perl, Python, and other extended forms)
- Object Schema: CORBA IDL, XML Schema, Relax NG
- Database Schema and Querying: SQL
Software Environment and Infrastructure Technologies
Here I include technologies I view as a part of the deployment
“environment” in which software runs, including the
infrastructure upon which the software is based. I group these
by technology family, and within each group, list its members
in chronological order of my initial exposure to them.
- IPC/RPC: Sockets, DCE-RPC, COM/DCOM, CORBA IIOP, Java RMI, XML-RPC, REST
- Filesharing: SMB/CIFS, NFS, WebDAV (at the protocol level)
- Data Persistence: Flat-file, RDBMS, Semantic Net, BTrieve/DBM, OO, ORDBMS, XML
Software Development Infrastructure Technologies
Here I include the technologies I view as a part of the process
of building software. This includes specific compiler suites,
toolchains, etc. This list is not exhaustive, but indicative. I
group these by tool family, and within each group, list its
members by my rating of their worth in solving the problem
(greatest to least.)
- Source Management: Perforce SCM, Subversion, CVS, RCS
- Dependancy Management: GNU Make, MS nmake
- Compilation/Toolchain: GCC+GNU toolchain, Borland C/C++, MS Visual C/C++
- Parsing/Lexing: ANTLR, PCCTS, Flex+Bison, Lex+YACC
Operating Systems / Platforms
Here I include the hardware and software platforms on which
everything runs, including “virtual” platforms
implemented on top of other environments.
- Hardware Platforms: Intel-based PC (from 8086 ISA through current technology, including PC104(+)), Motorola 68k-based Macintosh, PowerPC-based Macintosh, Sun SPARC-based workstations (5, 20, Ultra), Palm, Sony Clié, custom embedded platforms
- Operating Systems: MS-DOS, Microsoft Windows (3.x, 95/8, NT/2000, XP), Linux (Red Hat, Mandrake, Gentoo, LNX-BBC, LFS, Hand-built embedded), NetBSD, Solaris, Mac OS (pre-OS X and OS X), BeOS
- Virtual Environments: Cygwin, Java Virtual Machine (at the bytecode level), VMWare
- Networking Technologies: IP (TCP+UDP), DNS, DHCP, RADIUS, NTP, LDAP & A/D, Infoblox NIOS, 10/100/1000 Ethernet, cable plants (Cat3/5, termination), Fluke One-Touch, Fluke LANmeter, PathMaster, Net-Hopper switches, layer 0-8 troubleshooting and diagnosis (0: financial, 8: political), routing, switching, firewalls (ipchains/iptables/shorewall), NAT, IPSec, SSH, SSL, Ethereal (etc.)
General Productivity Applications and Technologies
It ought to go without saying that, as a seasoned software
developer, I know my way around just about any piece of software
into which I come into contact. However, every package has its
idiosyncrasies, so it's important to know just which ones I use
regularly enough to call myself “skilled” in them.
- Office Suites: Microsoft Office (through 2003, including XML), WordPerfect Office (through 10), StarOffice / OpenOffice 2.x (including XML)
- Graphics / Multimedia Tools: Adobe Photoshop, The GIMP, CorelDraw!, PageMaker, Macromedia StudioMX (Flash, Fireworks, Freehand, Dreamweaver), AutoCAD (including programmatic control via ActiveX and AutoLISP)
- Financial Suites: GNUCash, Quickbooks, Quicken, Microsoft Money Small Business
