  • WORK EXPERIENCE

    Senior Staff Software Engineer - Palo Alto Networks
    May 2020 - Present
  • Auto-Scale Platform - The new platform supports auto-scale service for multiple PA Mobile Device Services in more than 10k locations for more than 20m unique users. The platform offers flexible methods to adapt new scaling algorithms and schedules and can automatically resolve conflicts between different decision factors. The platform has been proven capable of handling usage explosion and tolerating system instabilities since 2020.
  • Usage Prediction - Designed and implemented an online prediction algorithm that automatically learns and predict usage pattern. The prediction guides auto-scale service in advance to better prepare for upcoming events.
  • IP Managment System - Designed and implemented an IP resource management system and an allow-list status feedback API. The system manages and pre-allocates IPs based on customer usage prediction and will only utilize the IPs that the customers have confirmed through the API.
  • Staff Engineer - Palo Alto Networks
    Nov 2018 - Apr 2020
  • Mobile Device Service Capacity Auto-Scale - Design and re-architectured the Global Protect Mobile Gateway auto-scale module. The new design reduced the communication and computation overhead and boosted the designed capacity by more than 1500 times. The new module successfully supported the dramatically increased load during the COVID-19 "work from home" transient period.
  • Instance Upgrade Workflow - Involved in designing and developing an orchestration workflow that performs upgrades to firewall instances.
