My career has followed a bit of a winding road. I started out in the financial markets: Risk Management for a major financial market clearing firm; partner in an Algorithmic Trading company; founder/owner of a hedge fund; president of a German Bank.

Then back to my roots as a software engineer developing low-latency, high-volume proprietary trading systems. I moved over to Web 1.0 as Amazon's first Sr. Principal engineer where I led a team building to replace the existing (monolithic) website architecture with one of the earliest Services-Oriented Architectures for a large-scale website. Also designed/wrote Amazon's RPC framework, standard service application framework, source code repository, build system, and a few other things.

On to Google, where I designed and led a team in the building of Millwheel, one of the earliest high-scale continuous computation frameworks, and finally now a Principal Engineer at Temporal Technologies, where we are building the foundation of a comprehensive set of tools for Cloud Applications.
