IndiaWhat I'm looking for
I am an AI Engineer independently building and deploying production-grade AI systems involving retrieval workflows, RAG pipelines, multi-signal escalation guardrails, and backend infrastructure on AWS, with a strong focus on operational reliability and real-world usage.
Built a production-grade multi-tenant AI automation system with multi-signal escalation guardrails that determines whether a query should be answered, refused, or escalated to a human before any response is generated — designed for high-risk environments across fintech, insurtech, legal-tech, and compliance-heavy workflows where incorrect AI outputs create operational and liability risks.
