Finn
AI Engineer
I'm Finn, an AI engineer. For the past two years I've been building LLM Agent systems — RAG retrieval, middleware orchestration, memory systems, and evaluation loops. I like turning ideas into things that actually run in production.
My core stack is Python + LangGraph, with Elasticsearch for hybrid search and vLLM for model serving. I built this blog with Next.js as a way to force myself to write down what I learn. I studied automation at NJUST and still have a soft spot for hardware.
