Fix Bugs in Next.js CRM with n8n Automation

We're seeking an experienced developer to debug and fix critical issues in a custom-built CRM using Next.js, integrated with n8n for automation workflows. Two major problems need addressing: a new lead does not appear due to an error in the n8n workflow, and appointment bookings fail entirely.

Responsibilities: Review current n8n workflows, identify syncing issues with leads, fix the appointment booking flow, conduct end-to-end testing, and provide a brief explanation of the fixes made.

Required Skills: Proficient in Next.js, n8n (workflow automation), Node.js, REST API integration, and debugging automation workflows.
