PSGTrades

A focused trading utility that routes one decision across multiple authenticated brokerage accounts.

Multi-account trading operationsAngular · TypeScript · AWS Lambda · API Gateway · Cognito · Tradier

Outcome

Reduced a repetitive multi-account workflow from roughly 50 minutes to seconds.

I built the Angular interface and AWS-backed order routing around the Tradier API, with Cognito authentication and token management. It demonstrates the same principle that guides my AI work: automate repetition while preserving explicit human intent.

Engineering signals

  • Multi-account order fan-out
  • Managed authentication
  • AWS serverless order routing
