La Brecha

Overview

A read-only public observatory that pulls scattered Argentine data — INDEC, BCRA, datos.gob.ar, private consultancies, Congress — into a single source. Two defining features: the gap between measurements of the same indicator across sources, and time series annotated with the political events that moved them. Formerly FinArg; rebuilt from scratch in 2026 after retiring the original Java/Spring stack.

The Challenge

Argentine economic data is published by a dozen institutions in incompatible formats, and the same indicator often has several conflicting values depending on who measures it. Reading a number without knowing which source it came from — or what happened politically that week — hides more than it explains.

The Approach

Three pieces with PostgreSQL as the contract between them: a Python scraper where each source is a self-contained connector module, a stateless FastAPI read layer with the calculators on top, and a Next.js App Router frontend that consumes it through a same-origin cached proxy. Schema changes go through Alembic migrations; the scraper runs on cron with a per-job CLI.

The Outcome

Live and ingesting continuously: 77k+ indicator rows across dozens of series, gap views, annotated charts, a Congress section, and a public API — all without login.
