PROJECT HIGHLIGHTS



  • Architected and prototyped node quorum algorithm for production Maps deployments. The result was that we moved from daily human intervention in production deployment plans to fully automated node eviction and an overall 40% reduction in activation time.

  • Architected and prototyped BitTorrent-based WAN data distribution service. This resulted in reducing daily average deployment time from 4 hours to 1h30m, and reduced daily egress bandwidth from our source data center by 85%.

  • Created reactJS + django service with the result of fully automating Maps environment creation. This transformed a week-long, error-prone manual process with hundreds of mutable properties into a repeatable one that takes 10-20 minutes on average.
