Thiago Ferraz
@thiagoferraz
I build production AI agents, LLM workflows, and automations that drive adoption.
United StatesWhat I'm looking for
I’m an AI Engineer and builder who ships LLM-powered features that actually get used. I’ve owned end-to-end problems by finding slow manual work, shipping a rough tool fast, then improving it from real feedback—like an agent that classifies inbound activity and can route, pause, or escalate with human review where it matters.
I engineer reliable LLM workflows using OpenAI and Claude APIs with tool use, structured outputs, and RAG grounded in vector databases via pgvector. I also build evaluation harnesses to keep quality and reliability measurable over time, and I’m comfortable driving adoption by translating complex technical work into plain language for non-technical teammates—plus wiring systems through REST APIs, webhooks, and asynchronous workflows.
