What I'm looking for

I seek roles building production LLM systems or ML infrastructure where I can ship scalable, secure AI products, optimize cost/performance, and grow technically.

I am a Generative AI engineer specializing in building LLM applications, RAG pipelines, and high-concurrency backend systems. I design and deploy production-ready systems combining LangChain, vector databases, and cost-aware model routing to deliver reliable, low-latency AI features.

At a startup I architected a Multi-Model Orchestration Platform that routes requests to 500+ LLMs and engineered real-time token streaming with SSE to reduce perceived latency by 40%. I also implemented enterprise-grade security, subscription billing integrations, and containerized AWS deployments.

My projects include hybrid RAG systems with NL-to-SQL guardrails, a multi-agent consensus engine for complex reasoning, and a high-precision bank statement transaction classifier optimized with Optuna. I bring practical ML, infrastructure, and backend expertise to ship robust AI products.
