AI automation engineer from Resistencia, Argentina (GMT-3) · open to remote contractor roles.

I spent 15 years running IT infrastructure for a provincial legislature: networks, servers and day-to-day support for non-technical staff. Since 2026 I build production software by directing Claude Code: I define the problem, review every change and verify it against real data before it ships.

Plant-to-patient traceability and back office for non-profits operating under Argentina's medical-cannabis law: plants, batches, irrigation and nutrient records, harvests, stock, patients, cash book and signed receipts.

• React 19 + TypeScript + Vite, Supabase (Postgres with row-level security), deployed on Cloudflare Pages
• Permissions enforced by Postgres, not the UI: RLS policies per role, so the API returns exactly what the screen would show
• 1,000+ unit tests and lint gating every pull request in CI
• Several independent installations for different associations, one in production with patient data
• Behaviour changes are planned spec-first with OpenSpec: proposal → spec → tasks, test-first

The Demo button on the login shows the interface only: that role reads zero rows.

I found that an open-source multi-tenant WhatsApp AI inbox exposed every tenant's pending message queue through the public API key. I reported it with a fix (revoking PUBLIC execute on the queue RPCs), and the maintainer merged it into main under my authorship: 28ef571.

• MCP servers in Python (FastMCP) that let an AI agent operate real systems within hard limits: read-only, no free-form SQL, sensitive data hidden by default
• WhatsApp AI agents on a multi-tenant platform (Next.js + Supabase), with a fallback chain across LLMs so a conversation never drops when a model runs out of quota
• n8n (1.5 years): job-search and recruiting pipelines, document OCR with local vision models, audio transcription
• Cloudflare Workers bridging IoT sensors (temperature, humidity, CO₂) into the app in real time
