SQL & ETL pipeline development
Pipelines that pull data from every app, clean it and land it where reporting and AI can use it: scheduled, logged and testable.
What we build
What we build with SQL & ETL
ETL pipelines
Extract from APIs, files and databases; transform with SQL; load into PostgreSQL.
Reporting models
SQL models and views that keep dashboards fast and consistent.
Data quality checks
Automated tests and alerts when data looks wrong.
Why Widle
Pipelines you can check, not just trust
We build pipelines when your data is spread across apps and spreadsheets, and make sure the numbers still match at the other end.
- 01
One source of truth
Consistent definitions so every team reports the same numbers.
- 02
Observable
Logs, retries and alerts on every run.
- 03
Tool-flexible
Python, SQL, n8n or a managed ETL tool: we pick the cheapest option that will still cope with next year’s volume.
