1. Ai Ml Engineer

   Pfizer

   May 2024 — Present · US

   Designed scalable diagnostic pipelines using Apache Spark and Airflow to process over 100 TB of neuroimaging data. Integrated with GCP AI Platform to orchestrate multi-stage ETL and accelerate deep learning workflows. Improved throughput for cognitive research models significantly.• Leveraged PyTorch and Hugging Face Transformers on AWS SageMaker to analyze unstructured clinical narratives from EHRs. Built custom embedding pipelines to generate longitudinal patient summaries, reducing documentation overhead and improving care plan personalization for chronic condition management.• Developed predictive modeling frameworks using Scikit-learn and XGBoost, applying Bayesian optimization and cross-validation techniques. Tuned features and parameters to improve neurological disorder detection, increasing F1-score and diagnostic precision across multi-hospital pilot implementations and anonymized patient cohorts.• Built interactive triage agents using GPT-4, LangGraph, FastAPI, and vector databases. Engineered retrieval-augmented generation pipelines and prompt tuning strategies, enabling real-time patient responses, and reducing clinical inquiry resolution times by 34% during care navigation trials.• Deployed production-ready ML models using Docker, MLflow, and GitHub Actions with CI/CD integration. Enabled automated deployment of inference services across cloud-native systems with rollback support, ensuring model version control, traceability, and uninterrupted availability in regulated environments.• Created clinician-facing dashboards using Plotly, SQL, and Statsmodels, translating complex model outputs into transparent visual summaries. Enhanced interpretability of risk scores and reduced onboarding time by enabling data-driven decision support through user-friendly, explainable AI interfaces.
