Looking for a jobFounder and Engineer
AI engineer building LLM agents at Em Camadas 3D and for restaurant operations, with database-enforced permissions and attack evals.
BrazilFounder and Engineer at Em Camadas 3D
About
I built an LLM WhatsApp ordering assistant for a restaurant client, now in operation, with permissions enforced in code and PostgreSQL rather than relying on prompts. I also reimplemented its permission layer as a public project, where a LangGraph agent uses database-enforced access controls and attack evaluations.
At Em Camadas 3D, I built Claude Code plugins and an MCP server for the Mercado Livre seller API, plus a human-in-the-loop content pipeline. My Ph.D. at University of Aveiro focused on fibre-optic battery instrumentation and machine-learning models that recover internal battery states from external signals.
