Responsibilities & Impact

  • Led backend development with Java & MongoDB for a healthcare prototype within an Agile environment, enabling efficient analysis of patient lab reports as part of a client project through the Centre for Digital Media.
  • Developed Python scripts for rapid prototyping to preprocess OCR output and test different LLMs for patient data extraction from lab reports, version-controlled with GIT to ensure reproducibility and smooth collaboration, accelerating evaluation and integration with Azure OpenAI.
  • Reduced setup time and enabled easy cloud deployment for the Providence HC project by deploying and containerizing backend services with Docker and Fly.io.
  • Reduced user workflow steps by 67% by creating an automated process that replaced multiple manual actions, resulting in a significantly improved user experience and effectively showcasing the prototype’s potential.
  • Integrated Generative AI capabilities using Azure OpenAI to address the challenge of interpreting test reports, collaborating with team members to refine LLM prompts, resulting in better extraction accuracy of patient data.
