Looking for interesting contracts, short or long-term.

Fifteen+ years of focused, highly-productive remote working experience.

  • User and administration guides — Maximizes customer success in deploying and using your product. Serves as a product sales aide, providing assurance to decision-makers that their employees will quickly learn to use the software effectively.

  • Product assembly/maintenance documentation — Reduces production errors, increases customer confidence in the product, reduces service calls and returns, and increases word-of-mouth promotion among peers.

  • Internal code documentation — Brings developers on-board more quickly while also serving as a code quality, code maintenance, and software quality check.

  • API documentation — Increases interest and uptake of your software product. Incidentally, it will also reduce software flaws as your API is thoroughly prodded for unexpected behaviours and side-effects.

  • Data analysis, transformation, and amalgamation — Leverages your data to its fullest extent. Reduces errors by schematizing data, enabling compliance and quality testing. Increases the value of your internal and external data resources.


Currently open to new contracts.

Work Samples

Avato provides expert integration services. Its flagship product is a hybrid integration platform that makes it easier to connect disparate data platforms through the use of open standards.

  • Avato Developers Guide — excerpts demonstrating detailed, cross-referenced insight into product configuration and integration tools (2020).

  • Avato Users Guide — A tour of the user interface and step-wise instructions for accomplishing tasks (2020).

  • All software developed for Avato was work-for-hire and is not available for review. Work included:

    • XSLT applications for transformation of EDI to XML;

    • XSLT framework for testing of endpoint services and for comparing expected versus received XML trees, including allowance for tag order and count differences;

    • Transformation of XML to XML, including collation of data from multiple endpoints;

    • Ant applications for building the Avato server;

    • Publishing pipeline supporting structured organization of Asciidoctor-format documentation into print-ready PDF and help system HTML content;

    • Other supporting work, including schema development, bug reporting, repository check-ins, research, and more.

Mandiant is a leading America cybersecurity firm, now a part of publicly-traded FireEye. My documentation for its “Mandiant Intelligent Response” product received praise as flawless in SC Media’s review of the software.

Meyer Sound is a renowned sound reinforcement technology company, having consistently advanced the technologies of loudspeaker design and aural space manipulation for more than forty years.

  • Compass User Guide — product installation, user interface, and tasks guide (2009).

  • All software developed was work-for-hire and is not available for review. Work included developing an in-house inventory control, inspection process, and defect-tracking web application; and developing pipelines for document publication.

LCS Audio developed SpaceMap, a thoroughly innovative multichannel panning system that used microphones, loudspeakers, and patented sound control techniques to deliver three-dimensional sound panning and environment control. The company was aquired by Meyer Sound in 2005.

  • CueStation Users Guide — an audio cue control hardware and software system that enabled sound designers unprecedented control and automation of stage and environment sound (2002).

  • Matrix3 System DSP EPROM Upgrade — stepwise instructions for end-user replacement of a key hardware component of the LCS sound control system (2000).

Documentation Habits

I like to write using plaintext markup. It is easy to work with, outlasts all proprietary formats, requires only a text editor, and is diff-compatible and VCS-friendly. ASCIIDoc and reST plaintext markup can be converted to Docbook XML and then published to web and/or print using HTML, PDF (via CSS or XSL-FO), or other destination data format, as demonstrated in most of the above examples.

I also publish documentation using InDesign, Framemaker, Word, etc. I’m comfortable in a Bash environment, several IDEs, various time-tracking and bug-tracking applications, and so on. I have messed around with a multitude of operating systems and programming languages, and read extensively on interesting programming topics.

When writing documentation I inevitably identify bugs, UX flaws, and other issues. I will happily log these issues and advocate for the best interests of the end user in determining the end resolution. Or not, your choice.

XSLT/XPATH-based Web Applications

This page is a web application written using XSLT Level 3, interpreted by Saxon-JS, with content transformed in-browser from XML data generated by Asciidoctor.js from a plaintext markup file.

Here are more XSLT web browser applications:

A simple ToDo App. Each UI element handles its own events. They share a common local persistent database.

The 2048 game. Keyboard events are captured at the DOM root. The relevant part of the browser DOM is transformed to a set of mapped data. An XPATH implementation of the 2048 game is applied against the captured data to calculate a representation of the next game state. Finally, the game state is updated. (To Do: improve touch event handling)

More to come as I find time to work on hobby code. I’m currently exploring financial APIs and the Meta-II metagrammar/metacompiler.
