Building reliable backends is what I enjoy most.

I work with Python, FastAPI, PostgreSQL, SQLAlchemy, Docker and REST APIs, building backend systems that are clean, testable and easy to extend.

I can help with: • REST API development • PostgreSQL & database integration • JWT authentication and RBAC • Backend debugging and bug fixing • API integrations and automation • Docker setup and automated testing

I’ve also built projects involving e-commerce workflows, payments, inventory, document processing, analytics, webhooks and workflow automation.

If you’re building a product, improving an existing backend, or need help fixing something that just refuses to work — feel free to reach out.

Available for freelance backend projects.

Hi Contra, I'm Thiago, an AI engineer from Brasília, Brazil.

This is Galley Brain, the multi-agent system I run on my own VPS. Each agent owns an area (finance, schedule, operations) and takes real actions through MCP connectors, with Telegram and voice as the interface. It started as my personal assistant and is turning into a product for restaurant owners.

I build RAG systems, AI agents and n8n automations for real operations. If you're working on something similar, let's connect.

Giving each agent a clear area makes Galley Brain easier to follow as it starts taking real actions. I'd add one approval screen that shows what each agent plans before it can change money, schedules, or customer records.
