I've been playing and DMing D&D since the Original D&D days :)
I've been writing software since my Commodore 64 was shiny and new, and have several Roll20 API scripts available including ScriptCards and Encounter Helper.
If you are interested in supporting my API development, I have a patreon account.
Finally, I have a discord server with Roll20 stuff as well as other nerd-interest things.
