This network will not only address the scaling limitations in Amazon's network, but will also provide intent based networking capabilities while enforcing zero-trust architecture. Within Intent Based Networking, I lead the Network Ops and Network Assurance space. My most technically complex project has been to design filtered replication protocol for two NoSql datastores to make Amazon's Stores businesses compliant with data localization laws around the world. The innovation was published by aws as a design reference until the feature set is natively supported by aws databases. My most impactful project has been to contribute to Amazon's Prime Video deal to broadcast Thursday Night Football exclusively. I was part of the team that enabled OAuth for Prime Video services. https://www.cnbc.com/2022/09/20/amazon-thursday-night-football-nfl-stream-draws-record-prime-signups.html I have been lucky to have experienced and learn from cultures in 5 different locations - New York, Seattle, San Francisco, Chennai and New Delhi.
