The challenge

Physicians, residents and medical students lacked a professional network built for how medical careers work — rotations, publications, mentorship, institutions — that was secure and scalable.

What we built

A serverless TypeScript microservices backend (9 services, 94+ handlers) on AWS Lambda/Fargate, a Python ML mentor-matching engine, and the full AWS platform as code in CDK v2 (11 stacks, 16 tables).

Systems delivered

  • User Service
  • Pages Service
  • Mentorship Service
  • Connections Service
  • Verification Service
  • News Service
  • Email Service
  • ML Recommendations Service (Python)

Outcome

Delivered the backend and cloud platform end to end, exposing a clean Cognito-secured API surface consumed by the client's React Native / Expo mobile app.
