Hyemin Kim
AI Solutions Engineer
I design AI systems in the language of the customer
and understand customers in the language of technology.
About
I sit at the intersection of AI engineering and customer-facing delivery.
At Squarelight, I own the full lifecycle of enterprise AI PoCs — from the first client meeting to architecture design, hands-on development, and final deliverable handoff. I translate business pain points into working AI systems, and complex technical concepts into language that stakeholders trust.
My background spans NYC business development, Google ML training, and bilingual communication (Korean/English, OPIc AL). This combination lets me move fast between boardrooms and codebases.
I'm looking for a role where I can keep doing what I do best: building real AI solutions with customers, not just talking about them.

My Role
Sole architect & developer — designed and built the entire system end-to-end.
What I Built
Built a full agentic RAG pipeline from scratch. The system uses BGE-M3 hybrid retrieval (dense + sparse vectors) with Qdrant, LangGraph-based agent that decomposes complex multi-hop questions into subtasks, and a 3-stage safety gate: domain classification → retrieval confidence → RAGAS faithfulness scoring. Supports real-time SSE streaming of the agent's reasoning process.

What I Built
Built an n8n-based workflow that collects news via RSS, clusters and selects topics through multi-stage Claude API prompt chaining, generates card-news content, renders images with Puppeteer, and auto-publishes to Instagram via Graph API. Runs autonomously every day.
