Engineering Director @ Directing Engineering From November 2014 to Present (1 year 2 months) Site Reliability Engineer @ Coding: python, bash Troubleshooting Linux systems. Creating, tuning, troubleshooting and testing monitoring rules. Creating, tuning, troubleshooting package/deployment configs. Wrote several design documents - Resource Utilization Based Balancing (internet traffic shaping). - Event Driven Monitoring (centralized, pub/sub capable monitoring) - Hadoop Monitoring (using OpenTSDB and tcollector): Implemented. From June 2014 to November 2014 (6 months) Site Reliability Engineer @ Coding: java, c++, python, javascript, R. Highlights: Linear regression analysis for scaling large distributed systems and capacity planning. Java, c++, python and javascript unit testing. Troubleshooting Linux systems. Creating, tuning, troubleshooting and testing monitoring rules. Creating, tuning, troubleshooting package/deployment configs. Created event handling and DOM transformation libraries in javascript which were used for customizing monitoring interfaces. I created the customization specification using json. Worked on a Python based coprocessor (used to add functionality to the Google monitoring systems) which is in heavy use, google-wide. - Made the main fetcher multithreaded. - Worked to turn the coprocessor into a service run by myself and a few other SRE (flesh out documentation, work with management and SRE). - Main author and maintainer of the load balancer fetching module (at the time of my leaving, this module accounted for ~80% of the traffic which was ~3000 qps). Added Data URI support (only image type) to Google Docs. - All Java w/Guice development. - Worked with three teams in three different timezones. Worked on a dependency flow chart system using Python and d3.js. - One implementation would display a chord graph of RPC calls between a single system and many systems. Wrote C++ libraries to set up callbacks from Google’s global load balancing system. - These libraries allowed clients to query Google’s load balancing infrastructure in order to “follow” other live services. - Several internal ads services in the review and crawl pipelines used these libraries as of March 2014.
