You will get A production AI agent trained on your own knowledge base
Project details
You know AI could help your operation. You don't know where to start, what's realistic, or what it would cost.
I'll map your current process, identify where AI agents genuinely fit, and give you an implementation roadmap with effort estimates — so you can decide with real information instead of vendor promises.
What you get: a process map, a prioritized list of automation opportunities ranked by impact and effort, a proposed architecture for the top opportunity, realistic savings estimates, and a written report with a 5-minute recorded walkthrough.
I build production AI systems for a living — multi-agent architectures, RAG applications and workflow automation. This audit is the same analysis I run before building my own systems, applied to yours.
Delivered in 5 business days. Fully async, no meetings required.

About Douglas
AI Engineer | Multi-Agent Systems, RAG & Workflow Automation
Sao Jose dos Pinhais, Brazil - 1:32 pm local time
Working solo, I've shipped: an AI agent hub with four specialized agents running in production for an editorial team; a diagnostic engine that cross-references five federal datasets to score risk across 5,570 municipalities in under five seconds; a generation-and-audit system for public procurement documents; and a project board that updates itself from voice input, with zero manual transcription.
The pattern across all of them: I turn messy human input — conversation, audio, scattered data — into structured, auditable output.
WHAT I DO
- Multi-agent architectures with human approval gates
- RAG applications over your own knowledge base (Supabase/pgvector)
- LLM orchestration and prompt engineering (Claude, OpenRouter)
- Workflow automation (n8n, webhooks, API integrations)
- Document generation and audit pipelines

HOW I WORK
Human approval on anything AI-generated that leaves your company. Every output traceable to its source. Multi-tenant isolation, agent versioning, and per-model cost governance built in from the start — because AI cost is the variable that kills margins.
I work async-first: written specs before we start, written progress updates, and recorded video walkthroughs at each milestone. You get more documentation than you would from a synchronous developer, not less. My spoken English is limited; my written and technical English is strong. If your project needs daily live calls, I'm not your best fit — if it needs someone who documents thoroughly and delivers on scope, I am.
BEFORE ENGINEERING
I spent 10 years as CEO of a B2B services company with roughly 400 active clients. I understand cost, margin, and deadlines — not just architecture.
Based in Brazil (GMT-3). Available for overlap with US and European business hours.
