  • Senior Site Reliability Engineer
    2015 - 2016
    • Grew the infrastructure out of one physical datacenter.
    • Configured direct physical connections between the physical datacenter and AWS through DirectLink.
    • Initiated full infrastructure orchestration and wrote 88k lines of Ansible playbooks.
    • Got 21 developers involved in contributing to the repo within a year after finishing the initial Ansible provisioning.

  • Senior Systems Engineer
    2009 - 2015
    • Designed and implemented the core infrastructure that runs on up to 80 hardware CentOS servers and on-demand AWS resources with up to 500 instances.
    • Provided system administration for the database, which was over 7TB in size with total caching of 2TB+. MongoDB's team claimed that we were the biggest client for their online backup solution.
    • Developed the system to be fault-tolerant. During a major datacenter failure (40% of all servers offline), the website stayed online through incoming traffic topping 1000 Mbps. It has since scaled up to 40 million monthly visitors, with 25k connections/second during peak load.
