My scope

The boundary I owned.

I built the product flow from React interfaces through Node APIs and Python engines, then migrated its infrastructure to AWS.

  • React
  • Node.js
  • Python
  • PostgreSQL
  • Docker
  • Terraform

Engineering evidence

  1. Translated engineering workflows into responsive analysis and visualization experiences used by two business groups.
  2. Hardened large calculation requests with schema validation, fallback defaults, structured errors, and asynchronous processing.
  3. Migrated services to Lambda and S3 with Terraform-managed infrastructure, reducing infrastructure cost by 60%.
OutcomeFaster simulation feedback with a substantially leaner cloud footprint.
