I build production systems end to end — from the type-safe backend to the interface, and increasingly at the boundary where LLMs meet real operating systems and real APIs.
- 🧠 Currently working on local-first AI agents with hard security guarantees — the model proposes, a deterministic policy engine decides.
- 🔍 I like problems where the interesting part is the constraint: guest-token auth, sandbox escapes, rate limits, output contracts that must not drift.
- 🧪 I ship with tests against captured fixtures, not against the live world.
- 🌎 Based in Argentina, working with distributed teams.

Browserless X (Twitter) scraper for Apify. HTTP-only against X's internal GraphQL with guest-token auth, a strict output contract, and a server-authoritative free-tier gate. 170 tests, all offline against captured fixtures — and a test that fails the build if a browser engine ever enters the dependency tree.
