about me past work

Who is this?

I'm a software developer. I was previously a senior software engineer and tech lead at Google, where I worked for about 7.5 years on Maps/Earth, Gmail anti spam, signup abuse and login security. In 2014 I left Google to focus on Bitcoin development full time. After two years of doing that, I joined R3 as the lead platform engineer, where I lead development of the Corda project.

I write a blog at blog.plan99.net, which covers a mix of programming, politics and economics.

You can email me at mike@plan99.net or visit my Google+ profile, or contact me on Freenode IRC where I go by the nickname "hearn".

Previous work

Before I worked on anti-spam, I was an on-call operator for Google Maps and Earth in the site reliability team, I worked on Windows emulation technologies and did various small contracts in the software industry.


I have given a variety of talks on Gmail, Bitcoin, Corda and the future in general.
