N8n Developer - AI, APIs, Webhooks

[For Hire]

I’m looking for freelance n8n work or a small team that needs an extra developer for client projects.

I’ve been building and testing workflows around AI customer support, invoice processing, lead qualification, Telegram assistants and client onboarding. Most of my work involves REST APIs, webhooks, JSON, JavaScript and LLM integrations.

I also work with Google Sheets, Drive, Gmail, Airtable, Telegram API, Docker and self-hosted n8n.

I’m mainly interested in implementation work — building workflows, connecting APIs, debugging integrations and getting automations working reliably.

Rate: $10/hour for smaller tasks and debugging. For complete workflows, I prefer project-based pricing depending on the scope.

Hi, I’d be very interested in joining you or collaborating as an additional developer on n8n client projects.

My background is focused on automation, AI integration, and digital transformation, and I’ve been working with n8n for building end-to-end business workflows, API integrations, AI agents, and production-oriented automation.

My relevant experience includes:

  • Building n8n workflows with REST APIs, webhooks, JSON, JavaScript, and external services

  • Integrating OpenAI/LLMs and AI agents into business processes

  • Google Workspace automation with Gmail, Google Sheets, Google Drive, and Google Calendar

  • Notion-based workflow and task automation

  • Docker and self-hosted n8n

  • Database/API integration and workflow orchestration

  • Human-in-the-loop and approval workflows

  • Error handling, debugging, retries, and improving workflow reliability

  • Automation use cases around document/invoice processing, customer support, reporting, task management, notifications, and operational workflows

  • Experience with Power Automate and broader enterprise automation, so I’m comfortable translating business requirements into technical workflows rather than only connecting nodes

I’m particularly interested in implementation and delivery work: understanding a client requirement, designing the workflow, integrating APIs, testing edge cases, documenting the solution, and getting it stable enough for real production use.

I’m also comfortable working as part of a small remote team, taking ownership of individual workflows/modules, debugging existing automations, or supporting client delivery when the team needs additional capacity.

If my background fits what you’re looking for, I’d be happy to discuss a small initial task or workflow first and see how we work together.

Best,
