n8n is a workflow automation platform that connects apps and APIs through visual workflows, with room for custom code and AI steps. An n8n developer turns a manual process, such as copying leads into a CRM, routing support emails or sending follow-ups, into a workflow that runs reliably without someone watching it.

Building the happy path is the easy part. The real work is what happens when an API times out, a record is missing a field or the same webhook arrives twice. That is what separates a demo from a workflow you can depend on.

Data handling: transforming JSON, matching records and writing small Code-node functions in JavaScript or Python.

Error handling: retries, error workflows, idempotent steps that don't create duplicates, and a visible place for failures.
