I’m an AI Engineer specializing in production-grade LLM systems, multi-agent orchestration, and scalable RAG pipelines on Microsoft Azure.
✅ 70% latency reduction (8.5s → 2.5s)
✅ 55% cost savings ($12K → $5.4K)
✅ 95% intent routing accuracy for 1,000+ enterprise users
✅ Strong focus on retrieval quality, evaluation, observability, and guardrails
✅ End-to-end delivery from LLM prototypes → full-stack production deployments
📅 Feb 2023 — Present
🧠 LLM Systems | RAG | LangChain | LangGraph | Azure OpenAI | FastAPI | Node.js
- Built an enterprise multi-agent AI platform with LangGraph (HR, IT, Legal, General Query) for 1,000+ employees
- Implemented GPT-4 based intent routing with 95% classification accuracy and 2s P95 latency
- Designed a production hybrid RAG pipeline for 50K+ ServiceNow docs using:
- Dense vectors (text-embedding-3-large, 3072-dim) + BM25
- Azure AI Search with metadata filtering + semantic reranking
- Achieved 0.89 MRR@10 and reduced irrelevant answers 35% → 4%
- Reduced response latency 8.5s → 2.5s using caching + parallel retrieval
- Added observability via LangSmith + Azure App Insights + guardrails (PII + RBAC)
- Reduced monthly LLM costs by 55% with prompt compression + model routing + caching
