James Singleton has been writing software since the days of the BBC Micro and has worked professionally in the .NET development ecosystem for almost a decade. He holds a 1st class degree with honors in electronic engineering and has designed and built his own (4-bit) microprocessor on an FPGA, along with a custom instruction set to run on it. He has a keen interest in information security and compression algorithms (particularly for media).

James has worked for many different companies on lots of varied and large-scale software projects, from stock exchanges to video encoding systems. He is part of the alternative Microsoft development (ALT.NET) and startup communities. James contributes to (and is influenced by) many open source projects and uses diverse technologies such as Python, Ruby, and Linux. He is enthusiastic about the direction in which Microsoft is taking .NET and its embracing of open source practices.

When not hacking code or writing for books and magazines James enjoys skiing, rock climbing, and craft beer. He also enjoys making Internet-of-Things projects, usually with a Raspberry Pi. He also runs the "CleanwebJobs" email list. This aims to get developers, engineers, managers, and data scientists into roles that can help tackle climate change and other environmental problems.
