What I'm looking for

I seek roles building production-grade GenAI/LLM systems with compliance, scalable architecture, multi-agent orchestration, and strong engineering ownership.

I am a senior LLM engineer with 14 years of enterprise software and architecture experience, focused since 2022 on production-grade LLM applications, compliance-driven RAG systems, and multi-agent orchestration. I have led architecture design, model selection, development, and production deployment for Fortune 500 clients, delivering measurable improvements in accuracy, compliance, and operational efficiency.

My projects include HIPAA-compliant medical terminology standardization, ESG compliance detection with >98% citation accuracy, and a ChatBI multi-agent analytics system that reduced query latency by 87%. I combine full-stack engineering, cloud-native practices, observability, and evaluation tooling to build secure, scalable GenAI solutions that drive business impact.
