Tools and Infrastructure team: Built, maintained, and improved a wide range of tools used by the software development team as the company scaled from 100 engineers to 1000+ engineers. This includes automated systems to build, and test over 1000+ packages.

Recent projects include:

Creation of a distributed caching layer for build system for intermediate and final build products, used to accelerate builds on a cluster of 200+ build servers. A Varnish cache cluster using SSD handled the bulk of the traffic. A cluster of golang servers handled all uploads of new objects and fetches for objects not in the cache. Objects were stored in a swift cluster, and the mappings between the objects stored in MySQL.

• Build/test log storage infra that provided local caching for most recent log, while long term storage used Google Cloud Storage for long term archival.

• Setup kickstart infrastructure to bring up new machines in build/test cluster.

Web security programmer - Wrote backend analysis program used to detect efficacy problems. Implemented scanning engine used to categorize webpages.

Network programmer - Wrote statistics collection infrastructure for K10 switching software.

Designed and implement software platform to support multi hop mesh network using standard 802.11 wireless networking hardware. The embedded platform runs GNU/Linux on a flash memory based file system. The mesh is used to support BACnet, a standard protocol for building automation and control systems.
