Santiago Cione

I am an automation and integration developer based in Buenos Aires, studying Computer Engineering at ITBA. Most of what I know came from shipping systems that real businesses depend on daily, not from coursework.

For a Madrid-based digital marketing agency I owned the automation layer across 15+ client accounts. That meant designing and maintaining n8n workflows for lead ingestion pipelines, centralized webhook hubs, conversational chatbots, AI lead qualification agents, and database reactivation sequences. I handled the full lifecycle: architecture, build, error handling, monitoring, and debugging production incidents. I worked with Meta Ads, GoHighLevel, Instantly, Slack, Telegram and Google Sheets APIs, with Supabase and Postgres as the system of record.

I now run my own automation practice serving small and mid-sized businesses in Argentina. My main product is a multi-tenant WhatsApp follow-up system built on n8n, the WhatsApp Cloud API, and a dedicated Postgres schema in Supabase. It handles quote follow-up sequences, appointment reminders and no-show recovery across multiple clients from one deployment, including Meta template versioning, webhook authentication, and per-tenant message accounting. I designed, built and deployed the whole thing myself, and I self-host the n8n instance it runs on.

I am also co-founder and CTO of Gercio, a restaurant SaaS for the Argentine market, where I own the technical side end to end on Next.js, Supabase and Vercel.

My core stack is n8n, Supabase and Postgres, Node.js, Python, TypeScript and Next.js, with the Claude API and GPT-4o-mini for agent work. I am comfortable with REST and OAuth2 integrations, webhook design, Docker, and running my own infrastructure on a VPS.

What interests me most is the unglamorous part: making automation reliable. Retry logic, idempotency, observability, and clear documentation, so a system still works six months later when nobody is watching it. I am looking for a remote role with a company building AI agents or internal automation at scale, where I can go deep on one system instead of spreading across many. I work as an international contractor, I am fully fluent in English, and I overlap comfortably with US Eastern and Pacific hours.
