Work Experience

VP of Engineering & Technical Co-Founder

Pandexio
  • Helped found a lean technology team for this startup, responsible for strategic partnerships, security and compliance strategy, technology operations, and system architecture.
  • Used API Gateway and DynamoDB via the Serverless Framework to expose ultra-scalable services, and used SNS and SQS messaging to elastically enable them to communicate in near real time.
  • Leveraged Auth0 to enable OpenID Connect-based authentication and authorization for back- and front-ends.
  • Harnessed AWS CloudSearch to construct a search domain, using incremental batch updates instead of completely re-indexing all data on an interval.
  • Built a real-time web sockets API, exposing all domain events via Pusher.
  • Enabled synchronization of server applications by publishing domain events to all webhook subscribers.
