Analytics Engineer · Data Engineer, based in Buenos Aires.
I've worked with data since 2020, and for the last three years I've been building and operating internal platforms: dimensional modeling, ELT pipelines, and REST, SOAP and ODBC integrations between databases and external systems.
The projects below are my own. All of them run on a schedule, in production.
One Airflow deployment that runs the BigQuery and dbt pipelines of two production projects without holding any business logic of its own. Each project mounts as a volume and brings its own DAG and credentials, so adding one touches three files.
Airflow 3.3 (CeleryExecutor) PostgreSQL 16 Redis Docker Compose
Timetables for the Tigre Delta passenger boats live in PDFs from three different companies. This parses them with pdfplumber — by colour and row position, not plain text — and normalizes the three sources into one relational model in PostgreSQL. On BigQuery, a dbt star schema: four dimensions, one fact table at a grain of one row per timetable entry × route, 31 tests.
The parser is the fragile part, so it has its own suite in CI plus a weekly check against the live sources to catch format changes before they break the app.
Django pdfplumber PostgreSQL BigQuery dbt Airflow pytest Docker
Two official APIs publish tide height and weather for Argentine river stations, but only as a rolling snapshot — yesterday's readings are gone. A daily Airflow DAG loads them into BigQuery with an incremental MERGE, so history accumulates instead of being overwritten. dbt builds a staging model per source and a mart joining tide and weather by station, date and hour, with tests for freshness, duplicates and forecast staleness.
The dashboard doesn't read from the warehouse: it reads a local per-station JSON cache, so the page stays fast and keeps working if the pipeline is down.
Django BigQuery dbt Airflow Docker vanilla JS
Fret position calculator for string instruments, with 1:1 scale printable plans in PDF. No database — pure calculation, service layer kept out of the views.
