AI engineer and backend developer (Python and TypeScript), based in Asunción, Paraguay. I build AI agents that run in production, from architecture to deployment, with Claude Code, LLMs, RAG and MCP. Looking for a remote role, open to full-time.

The production systems I built belong to the companies behind them, so the code is private. Context on LinkedIn:
- Zapix Pay (Pix payment gateway; I built the backend and DevOps, co-founder and partner): BRL 1M+ processed. I built durable queues, idempotency and payment reconciliation so that no charge is lost or duplicated. TypeScript, NestJS, Next.js, PostgreSQL, Prisma.
- Alltius.dev (software engineer, automation and AI agents; partner): I built more than 10 AI agents that run in production for clients. Python (FastAPI), TypeScript, RAG, MCP, n8n.
- Academia de Contadores (AI, automation and security): built an AI-powered CRM (a Chatwoot fork) that unified 15,000+ contacts from three sources; implemented a RAG agent for each of 20+ mentees; built an agent that queries the CRM through MCP; moved secrets to Infisical and servers behind a private network.
Availability: my day-to-day work today is at Academia de Contadores only. At Zapix Pay and Alltius.dev I am a partner and no longer in the daily operation. If I join a team full-time, I hand over my Academia role to colleagues and partners, and the handover is ready.
Public code is pinned below. I design the architecture and build with Claude Code and Codex.
