About

I build and lead teams that tackle complex, large-scale challenges in everything from AI, to distributed systems, to programming languages. Transforming poorly-defined problems into finished solutions really motivates me. I’m comfortable working across different levels of abstraction: implementation-level, team-level, organization-level. I like working with teams that seek out data and second opinions, to refine and improve ideas throughout the development lifecycle.

      Lead a 15 engineer team supporting the Python programming language at Google. We supported our AI customers (DeepMind, TensorFlow, etc.), as well as other large users of Python like YouTube. Our biggest accomplishment in my tenure was migrating the world's largest Python codebase from Python 2 to Python 3. This was a huge effort involving cooperation from hundreds of teams across Google. Through automation, my team was able to save Google hundreds of engineer-years worth of toil as we migrated the code base.

  • R&D Software Engineer at Agilent Technologies
    May 2006 - Sep 2010 · 4 yrs 5 mos

    While at Agilent, I was the lead engineer behind Command Expert: http://tinyurl.com/AgilentCommandExpert This is a PC application to integrate electronic test integration into Excel, Matlab, LabView, and other analysis applications. I came up with the basic idea, worked with customers to make it better, and implemented most of the UI. Prior to that, I worked on programming languages and user interfaces for distributed, real-time systems. This work was focused on electronic test customers who were using IEEE 1588 for clock synchronization in measurement applications: http://www.nist.gov/el/isd/ieee/ieee1588.cfm
