    Designed and re-factored the auto-scale module to support multiple metrics from multiple data sources, including predictive metrics and real-time metrics. The new architecture gives SRE flexible choices to deal with a variety of scenarios without an increased workload. The new architecture allows multiple metrics to be evaluated without conflict.

    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.
