End-to-End Ownership

  • Own AI systems from:
    • Design → Development → Production
  • Handle:
    • Monitoring & observability
    • Cost optimization
    • Failure modes and reliability
Data Pipelines & Evaluation

  • Develop pipelines for:
    • Data ingestion
    • Processing
    • Evaluation
  • Build dashboards to monitor and improve model performance
Product Integration

  • Integrate AI models into core healthcare products
  • Improve automation, accuracy, and user (doctor) experience

Cross-Functional Collaboration
