What I'm looking for

I’m looking for remote AI Engineer roles where I can independently ship production AWS + RAG/LLM systems—especially multi-agent pipelines with strong deployment, monitoring, and reliability. I’m excited by teams that value clean engineering and real-world impact.

I’m a CrewAI Expert AI Engineer with 7+ years of enterprise infrastructure experience, and I focus on independently shipping production-grade AI systems on AWS. I build hybrid multi-agent workflows using CrewAI + LangGraph, selecting the right control-flow pattern for the job.

In production, I’ve deployed systems on AWS ECS Fargate with S3 persistence, ECR containerization, Secrets Manager for secure credentials, and CloudWatch monitoring. I orchestrated an end-to-end hybrid multi-agent trading pipeline with LangGraph Advanced typed StateGraph conditional routing and checkpointing, while also building a zero-hallucination RAG pipeline (LangChain + FAISS + GPT-4o-mini) that’s live on Vercel.

I’ve delivered 4 live AI products across document intelligence, voice AI, and LLM integration, including a speech-based expense tracker and an AI Excel formula generator. I’m also DeepLearning.AI/Andrew Ng certified (3×) and I’m open to remote AI Engineer roles globally.
