Programming and Software Development
I build Wordpress sites, Facebook apps and write light-weight CMS and related web apps. I migrate databases, integrate rich media content and open source applications and I manage R&D projects. I like researching vendors and technologies and working with people to find the best IT solutions.
I have been writing software professionally since 1996. I have experience with the following technologies: (open source) PHP, Javascript, JQuery, Perl/CGI, C, C++, SOAP, JSON, XML, CSV, Linux and MySQL, and (Microsoft) Win32 SDK, VB, ASP, COM, MS-SQL, IDL, MSMQ.
I get asked a lot what tool I use to create websites. Except for great libraries (like JQuery) that run on the server, I have been writing my own tools since Day Two. When I first got into HTML authoring, I tried Dreamweaver and quickly learned that the GUI wouldn’t let me do what I knew was possible and I wound up coding in their "code viewer". So I abandoned Dreamweaver and did a lots hand-coding of HTML. I learned how to make fast pages that are compatible across browsers, easy to modify and keep the browser out of "quirks mode."
Then I wrote Perl and PHP scripts and templates to automate the process. I wrote Perl scripts that write Perl/PHP scripts and data-driven script generators - PHP apps that turn XML files into DHTML (Javascript + HTML).
I don’t know if this qualifies as AOP (aspect-oriented programming). I am just looking for the productivity gain. I like writing reusable, productivity-enhancers, because I see a gap in real-world operations and one-size-fits-all solutions. See my projects page for more on this.
Past Projects
Online multimedia investor presentation
Create online multimedia investor presentation. Powerpoint has limitations that make it less desirable for fast, rich online presentations. We wanted to integrate various media types, Flash, voice-overs and background music and by mixing Flash, frames and DHTML, I created a presentation that was modular, easy to modify and upgrade incrementally.
Productivity Application
Web-based in-house sales ticket tracker that integrated three business units, increased transparency and enforced policies that cut costs and increased revenue. The solution was a Perl/CGI + DBM web application because the customer has a very heterogeneous server environment. This Perl program cost far less than customizing the accounting system.DIBOL Database Migration
Imagine putting your business into a World War I biplane every morning and flying it over the Grand Canyon. Well, that it what this business was doing with their mission-critical, proprietary database application. The hardware had been old enough to vote since the early 90’s. The companies that had built the various components had long since been bought and dismantled, and the software was hard-coded to it. Libraries and drivers had been deprecated decades ago. And of course, the entire ball of mud was thoroughly undocumented and unintentionally booby-trapped. Staff operations were not only undocumented, but laden with superstitions and magic keystroke combos that were handed down from the early times. No one single person fully understood what the app did, how it worked or whether it was working correctly. But because the application performed a mission critical, core business function, upgrading that software and hardware was like changing the piston rings while the motor was running. And yet me and my colleague did it. Today, that same app runs on a state-of-the-art firebreathing monster. The business unit has never gone down and a plan is in place to migrate the app going forward.Scientific Instrumentation
This desktop application performs a significant amount of data conditioning, file I/O, and printing – all of which went in a headless multi-threaded DLL. The data reporting model allows the client to make asynchronous queries and redirect the results individually. The raw data cache provides a data abstraction layer so the data conditioning code does not know whether the data came from the port or a file. The post-conditioning data cache allows the GUI to query without re-processing (which would be perceptible to the User). Finally, the GUI exe has a representational data cache because the User chooses a particular view of the data. This made the GUI client a little fatter, but it is GUI logic. The container class allows the client application to easily describe new representations, not just the ones in the specification.
Keystroke Redirection Service
"KeyJack" is a keyboard utility that redirects function keys to the console. It was developed for a terminal emulation project that needed to send keyboard commands over a telnet session.
