Senior AI Engineer

• Set up and clustered two NVIDIA DGX Spark nodes to host and serve models on-prem, including air-gapped workloads.
• Built a GenAI platform end to end on FastAPI, React 19, Neo4j and ChromaDB: hybrid GraphRAG retrieval, answers streamed over SSE, and multimodal OCR pipelines.
• Brought a critical offline platform on RHEL and Docker Swarm back to life: upgraded 15+ microservices, then ran a PostgreSQL disaster recovery, salvaging data from a replica, rebuilding the corrupted primary and finishing the migration.
