Projects:

• Loadbalancing
  • I do not write the loadbalancer. I configure and deploy it in production for all Google services that speak HTTP/HTTPS. I am an expert in these systems, and on tweaking and tuning them to meet the specific requirements of varied services.
  • I have led or participated in several teams that have altered the architecture of the production systems on the site with no downtime and no public maintenance windows.
• Ad Hoc Software Development
  • A big part of the job is writing configuration storage, validation, and glue code to get configuration deployed safely. Most of this is done in Python.
• Oncall Engineer
  • Literally carry the pager for google.com. I have dealt with network issues, massive scale software bugs, DoS attacks, and anything and everything else that comes with running a large web site on the internet.
