• Implement comprehensive LLM evaluation frameworks with automated pipelines, custom metrics, benchmark datasets, and safety guardrails ensuring regulatory compliance
• Build end-to-end MLOps pipelines for model training, deployment, monitoring, versioning, and automated retraining with drift detection
• Develop predictive models for compliance risk scoring, regulatory change impact, anomaly detection, and time-series forecasting
• Write production-quality Python code for data processing, feature engineering, API development (FastAPI/Flask), and ETL/ELT workflows
• Lead A/B experiments and product analytics to measure AI feature impact and drive data-driven decision-making
• Create explainability frameworks (SHAP/LIME) and monitoring dashboards ensuring transparency and regulatory adherence
• Collaborate with cross-functional teams to translate business needs into ML solutions and communicate insights to stakeholders
