Senior AI Platform Engineer at EY, shipping production LLM and RAG systems with repeatable CI/CD on AWS and Azure.
United StatesWhat I'm looking for
At EY (Vanguard), I run production LLM and RAG serving on AWS Bedrock and Azure OpenAI, with autoscaling and caching for enterprise traffic. I also built containerized CI/CD that makes GenAI releases repeatable and recoverable.
At ECS (USPS), I owned Kubernetes/EKS inference endpoints for federal LLM and RAG services with 99.8%+ uptime. I automated validation through serving and monitoring, cutting model release cycles from days to hours, and built OpenSearch vector retrieval with RBAC and encryption for FedRAMP mission-critical search.
