At Expedia Group, I automated AWS Palo Alto Non-HA Firewall failover with Python-based serverless workflows, cutting failover time from 40 minutes to 90 seconds.
I also eliminated AWS S3 cross-region replication lag, reducing errors from undiscovered data by 75%. My work included automating decommission and rollback processes that sharply reduced processing and cleanup times.
As a Software Development Engineer I, I developed a Python and AWS Lambda network device upgrade system that reduced the upgrade cycle by 85% and saved more than 1,100 person-hours. I also built real-time monitoring dashboards and synchronized ServiceNow with internal network inventory using Python APIs.
