I build reliable lead workflows using n8n + Airtable + Slack + Gmail—from intake and routing to activity logging, alerts, and follow-ups. Each build includes error handling (retries + fail alerts) and a clean handoff (SOP + test payloads) so your system stays maintainable. If needed, I also add AI steps (Gemini/LLM) for email triage, extraction, and draft replies with a review flow.
