n8n & API Integration Specialist | Custom Automation & FastAPI

Your n8n workflow works - until it needs a custom API connector, proper error handling, or logic no built-in node covers. That's usually where automation breaks, because most "n8n experts" have never written backend code. I'm a backend developer with 7+ years building production systems, now focused on automation and API integration. I build workflows that don't just connect apps - they handle edge cases, retries, auth, and the messy parts of real APIs. What I do: - n8n workflow design, debugging, custom node/API integration - REST API integration (auth flows, webhooks, rate limits, error handling) - Lightweight backend services (Python/FastAPI) to fill gaps no-code tools can't - Standalone Python scripts, data processing/analysis, and small backend tools - even outside of automation/integration work -Docker-based deployment for reliable, repeatable automation I've worked on GCP-based production systems and understand what breaks automations at scale - not just how to wire two apps together. Also open to smaller, self-contained Python projects - scripts, data cleanup/analysis, quick backend features - with or without any automation platform involved. If your automation keeps failing on edge cases, or you need something beyond drag-and-drop, let's talk about your workflow.
