  • 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.

  • RightScale (Development)

    While working remotely with various projects built on top of AWS, I encouraged my clients to use as a management platform for their autoscaling features.
