I will build n8n automation workflows and API integrations
Burak Demir
About this gig
Most n8n workflows are easy to connect. The real challenge is making them reliable when data is duplicated, invalid, incomplete, or an API behaves unexpectedly.
I build reliable n8n automations, API integrations, webhooks, and PostgreSQL-backed workflows designed for real business use.
Depending on your package, I can build or improve:
n8n workflow automations
REST API and webhook integrations
CRM and lead workflows
Data validation and normalization
Error handling and conditional logic
Database-level duplicate protection
PostgreSQL storage and audit logging
Workflow testing and troubleshooting
My approach focuses on reliability, traceability, and maintainability not just connecting nodes until a demo works.
I have also built and tested a reusable n8n + PostgreSQL automation foundation that handles valid, duplicate, and invalid requests with automated reliability tests.
Message me before ordering if your workflow involves multiple APIs, custom business logic, or an existing system that needs troubleshooting.

FAQ
Can you fix an existing n8n workflow?
Yes. I can troubleshoot existing workflows, identify failed logic or integrations, and improve reliability, validation, and error handling.
Can you integrate custom APIs and webhooks?
Yes. I can integrate REST APIs and webhooks when the required API documentation and access are available.
Can you use PostgreSQL with n8n?
Yes. I can use PostgreSQL for persistent data storage, duplicate protection, audit logging, workflow state, and business logic.
What do you need before starting?
I need a clear description of the workflow, the applications or APIs involved, sample input/output data, and relevant API documentation. Credentials can be shared securely after the order begins.
Which package should I choose?
Choose Basic for a small workflow or fix, Standard for a business workflow with validation and multiple integrations, and Premium for PostgreSQL-backed automation with advanced reliability features.
