What I'm looking for

I’m looking for a team where I can lead end-to-end GenAI implementations—especially LLM/RAG and multi-agent systems—translating messy requirements into PRDs, PoCs, and production-ready roadmaps that drive real business outcomes.

I’m an AI Engineer and strategic consultant with a proven track record of bridging the gap between complex business challenges and scalable technology solutions. I build end-to-end architectures—from LLMs for classification tasks to Retrieval-Augmented Generation (RAG) pipelines—while leading client discovery to diagnose operational pain points.

I translate ambiguous, high-level visions into structured technical roadmaps and actionable deliverables, keeping advanced data science tightly aligned with measurable business value. Recently, I integrated an open-source MCP Server into an enterprise-connected conversational chatbot, supported SOC workflow diagnosis with custom query tools, and defined evaluation parameters for multi-agent systems in high-stakes environments.

I also drive execution by decomposing “messy” requirements into PRDs, epics, and user stories, then validating PoCs with C-suite stakeholders—so teams can move from strategy to measurable automation.
