What I'm looking for

I'm looking for remote B2B contract work. I’m based in Brazil and work in GMT−3.

At AgentStack.tech, I designed and shipped a live multi-tenant platform that AI agents operate through one MCP endpoint, with 752 public actions across 59 domains. It’s listed in the official MCP Registry and earns revenue from paying clients.

I founded and solo-architected AgentStack from an empty repository, creating a unified MCP and REST surface with TypeScript, Python, and React SDKs. I also built a custom RAG engine and an AI Builder orchestrator with validation and repair loops.

I keep the platform’s architecture and access controls coherent with documented decisions, CI audits, tenant isolation, and role-based access. A templating-syntax failure pattern led me to redesign the command and template contract so the conflict became structurally impossible.

Before AgentStack, I shipped multiplayer and action games at Dreamfrost Studio, Toadman Interactive, and ArtPlant, and built cloud-backed multiplayer services at World4Play. My work has spanned production backends, real-time systems, and games across PC, consoles, and mobile.
