Vinícius Raposo (FishRaposo)

AI Reliability Strategist — I build the systems that work while you don't.

Most LLM demos look impressive until they meet real users, messy data, edge cases, latency, cost limits, weak retrieval, and broken workflows. The model call works. The system around it collapses.

What I Do

I help founders and small teams turn fragile AI prototypes into production-ready systems:

  • RAG pipelines that retrieve the right context and cite sources
  • Agent workflows with clear tool use, failure handling, and human override
  • Guardrails that reduce hallucinations, compliance mistakes, and operational risk
  • Evaluation paths, observability, and audit trails
  • Clean architecture and handoff docs your team can own

Proof

  • WCP Compliance Agent V5 — Five-service monorepo for WH-347 payroll compliance. React 19 · Vercel AI SDK · FastAPI × 2. 271 tests, 0 failures, mock mode with zero deps. Repo: github.com/FishRaposo/WCP-Compliance-Agent-V5
  • 7 production AI systems shipped at Expat Money (GPT assistants, RAG workflows, scraping pipelines, automation tools)
  • LangChain contributor — production-focused PRs

I don't sell chatbot wrappers. I build the infrastructure underneath them.
