AI & agents

I build and operate AI agents in production.

In oblex.cl, an agent answers regulatory-compliance questions with retrieval-augmented generation (RAG) over each institution’s regulations, and calls tools to query that institution’s own database. It runs on LangGraph.js over a self-hosted runtime (skein-js), not on a managed platform — the same reason I self-host the rest of that backend.

I also shipped an MCP server (api.oblex.cl/mcp) so oblex can be used from ChatGPT, Claude or any agent, scoped to the account that authorises it.

I choose the model per use case instead of defaulting to one, and I use coding agents (Claude Code, Cursor) as part of my daily flow — setting the architecture, the patterns and the review criteria, and staying accountable for what ships. The code that goes to production is mine.
