Key Strengths

  • Improved clinical text classification accuracy ~20% by fine-tuning BERT on EHR data
  • Built domain-specific preprocessing/tokenization (custom vocab, abbreviation standardization, dataset balancing) to reduce noise and boost model performance
  • Entity resolution across patient/provider systems using fuzzy matching + manual validation/tuning
  • Improved semantic linking/search relevance ~25% via domain fine-tuned embeddings (e.g., linking 'heart attack' and 'myocardial infarction')
  • Designed production-grade Python data workflows with Airflow + AWS Glue, logging/monitoring in CloudWatch, and Git versioning
  • Reduced fraud detection pipeline runtime ~40% at Wells Fargo by modularizing AWS Glue workflow, enabling parallel tasks and reusable components
  • Moved models from notebook experimentation to production using AWS SageMaker pipelines with reproducible tracking/versioning

Built and shipped a production LLM-powered decision system that replaced a slow, inconsistent manual review process by turning messy text into structured, auditable outputs behind an API. Demonstrates strong end-to-end ownership of reliability and operations (schema validation, retries/fallbacks, latency/cost controls, monitoring for drift) and a disciplined approach to evaluation and regression testing. Experienced collaborating with non-technical reviewers to define success criteria and deliver interpretable outputs that get adopted.
