Building and deploying production-grade AI/ML models on Vertex AI, BigQuery, and Dataflow.
Operationalizing MLOps and AI Ops frameworks for speed, reliability, and compliance.
Embedding LLM-powered agents into clinical workflows and patient-facing applications.
Applying cloud-first design principles with modern stacks (Kubernetes, Terraform, Docker) to ensure scalability, security, and interoperability.

With more than a decade of experience in value-based care, Lumeris combines deep healthcare expertise with a startup mindset in tech innovation. Every project directly impacts patient health, provider satisfaction, and the way care is delivered at scale.
