Building software since 1999, and trading systems since 2008.

I started out on satellite communications, then ran my own company for six years building a web and video conferencing system that more than 200 organizations licensed. Since 2008 I have built trading systems end to end: market data, order gateways, exchange certification, strategy frameworks, simulators, and the research that runs on top of them, across fixed income, futures, equities, options and crypto.

Everything in this workshop grew out of that work. MTS is the trading system itself and the toolbox I use to check it. Memory is what I built when my AI tools kept forgetting what the last session had learned. Palmtop and Desk are the small apps and desktop tools I wanted and could not find.
