ArchaeoSim 4 is the first major teaching simulator on my new HTML5 CourseWare base. It debuted to undergrads at Yale University in Fall 2014.
ArchaeoSim explores sudden climate change in a rain-fed farming civilization in ancient Mesopotamia.
Tech: Cross-browser, including mobile.
Three Pond Chemistry apps are the first of my new HTML5 CourseWare to reach Yale grad students. An animated pond is paired with worksheets to explore solubility, acid-base equilibria, and air-water partitioning.
Coming soon, HTML5 ports of my five apps for the award-winning Habitable Planet course for Annenberg Learner.
Tech: Cross-browser, including mobile.
My latest book is E-Cigarettes 102: DIY E-Liquid, sequel to E-Cigarettes 101: How to Start Vaping.

I know, the stereotype is that programmers can't write. I love writing.
Architected and implemented a custom e-Commerce site. This American manufacturer provides manufactured to order parts for power plants.

Mandalar is the classic children's pattern blocks, only better. Mobile touchscreens are a natural for this math manipulative. Tap to rotate, snap 'em together. Zoom in, zoom out, group, scale, color - even draw fractals. Fills the screen from mobile phone, to tablet, to 24" monitor, to SmartBoard. Check out my NumBlox cuisenaire rods, too.
Tech: ActionScript 3/AIR for single-source apps for iOS, Android, and desktop.
I'm a freelance web programmer, focused on interactive graphics. I've been developing for the Internet since 1994.
My special niche is advanced science teaching simulators for universities such as Yale. I also subcontract for interactive marketing firms, bidding and implementing the tricky parts, such as product configurators, or a custom data-driven interactive map.
I focus on single source technologies for cross-browser, cross-platform support, including mobile. I do the full software life-cycle, software architecture through specification, design, development, documentation, deployment, and ongoing support. Or whatever subset you need.
Generalist expertise includes:
Please see my Portfolio of simulators and other online applications. And my Resume.
I also love to write - both technical writing and fiction, plus a bit of graphic storytelling (manga and story illustrations). Excel at specifications, proposals, and documentation. My latest book is E-Cigarettes 102: DIY E-Liquid.
