AI Automation Expert | n8n & Workflow Architect | Make | Zapier | API I'm an AI Automation Expert, n8n Developer, and Workflow Architect — also working as a Zapier specialist and expert, Make specialist, and API integration developer. I build n8n workflows, Make scenarios, and Zapier automations, plus custom API integrations, AI-powered systems, and CRM automation that takes manual work off your plate. As an automation specialist, backend API developer, and integration expert, I architect systems with proper error handling, retries, and logging, so every workflow keeps working reliably, not just in the demo. WHAT I DO n8n: as an n8n developer and workflow expert, I build custom JavaScript code nodes, self-hosted Docker deployments, and API-to-API bridging for systems with no native connector. Example: I fixed a failing n8n workflow by migrating it off a deprecated API endpoint and building dynamic date-window logic within the API's limits. Make: as a Make specialist, I build scenario-based automation for AI content pipelines. Example: I fixed a Make scenario where AI-generated bulletins had broken links — the cause was Make resolving API variables before the AI prompt — by restructuring the automation and adding an AI self-check step. Zapier: as a Zapier specialist and expert, I deliver fast, reliable Zapier automation when speed matters more than deep customization. A well-built Zapier workflow often solves in an afternoon what would otherwise need a custom developer. API Integration: as an API developer, integration specialist, and API expert, I work with REST APIs, webhooks, custom backend endpoints, and CRM schema design — connecting CRM platforms and systems that were never built to talk to each other. AI Automation & AI Agents: as an AI automation expert, I've architected AI-powered SaaS MVPs (e.g., an HVAC revenue-recovery agent using Next.js, Supabase, Gemini/OpenAI, Twilio, Vercel) and AI content pipelines with built-in validation so AI output doesn't ship broken. CRM Automation: as a Frappe CRM developer, CRM specialist, and CRM automation expert, I build self-hosted, Dockerized Frappe CRM setups — custom doctypes, backend API routes, messaging integrations — plus HubSpot CRM workflow automation (lead routing, follow-ups, data sync) as a dedicated CRM specialist. Communication Automation: WhatsApp integrations (e.g., Wazzup24) wired into your CRM, SMS/voice via Twilio, and automated email/document generation. REAL PROBLEMS SOLVED - Fixed a silently-failing n8n workflow by rebuilding deprecated API date-window logic correctly. - Fixed a Make automation shipping broken AI-generated links via corrected variable order and self-verification. - Built a WhatsApp-to-CRM automation from scratch inside a self-hosted Frappe CRM, including custom data modeling and backend API contracts. - Architected an AI-powered lead-recovery workflow for HVAC businesses. WHY WORK WITH ME As an automation expert, I debug as much as I build — fixing broken or undocumented n8n, Make, or Zapier workflows, not just creating new ones. I scope realistically, favor a working v1 over an overengineered workflow, and document everything so you're never locked in. As a full-stack automation developer, I work across n8n, Make, Zapier, and backend API development, so I'm not stuck when a no-code tool hits its limit. INDUSTRIES: professional services, home services (HVAC), SaaS products, and agencies that rely on CRM and workflow automation daily. TECH STACK: n8n, Make, Zapier, JavaScript/Node.js, Python, OpenAI, Gemini, Frappe CRM, HubSpot, Twilio, WhatsApp APIs, Next.js, Supabase, Vercel, Docker, Notion, Revolut API. HOW WE START: message me with what's manual or broken, which CRM and API tools are involved, and roughly what volume you handle — I'll reply as an honest automation expert with a clear scope and approach. As your n8n, Make, and Zapier developer, I test failure conditions, not just the happy path — what happens when an API times out, a webhook fires twice, or a CRM field is empty. I build idempotency checks so retried events don't trigger duplicate CRM records. I keep every API credential in proper vaults, never hardcoded into a workflow. Whether it's one Zapier automation from a Zapier specialist, a complex n8n workflow from an experienced n8n developer with AI decision-making, or a full CRM overhaul from an API integration expert, I bring the same approach: understand the process, design for edge cases, build it properly, and hand over a documented, working automation in your own accounts. Message me what's manual, broken, or missing in your CRM or workflow, and I'll tell you honestly, as your automation developer, specialist, and expert, how I'd approach it with n8n, Make, Zapier, or a custom API integration.
