Implement MLOps and LLMOps practices, including version control, CI/CD, containerization, model and prompt versioning, monitoring, and incident support.
Apply privacy, security, identity and access management, responsible AI, and model-risk controls appropriate to a regulated environment.
Partner with stakeholders to clarify use cases, assess feasibility, define acceptance criteria, demonstrate prototypes, and transition solutions into production.
