Where You Are Today

We've taken the time to deeply understand your current situation. Here's what we identified.

🏚️

Click-and-Connect Automation That Collapses Under Real Load

Workflows stitched together without architecture look fine in demos and break in production — missing error handling, no retry logic, hardcoded credentials. When a step fails at 2am on a Saturday, nobody knows until a deal is already lost.

🤖

AI In the Stack With No Output Guardrails

Calling an LLM inside an automation is easy. Getting it to return structured, parseable output that downstream nodes can actually act on is an architecture problem. Unguarded LLM calls are the single most common workflow failure point.

📦

Systems Nobody Else Can Maintain

When workflows ship without documentation, an error handling map, or plain-English explanations, they become a black box. The moment the builder is unavailable, operations stall and the system can't be safely extended or debugged.

A Production n8n Architect Who Designs Before Building and Documents Everything

I start with the business problem — mapping data flow, identifying failure points, and designing the architecture before touching a single node. Then I build: custom JavaScript nodes, structured LLM prompts with parseable outputs, human-in-the-loop approval gates, retry logic, contextual error logging with actionable alerts, and GDPR-compliant data handling. Every workflow ships with a JSON export, credential best practices, an error handling map, and a plain-English walkthrough your team can actually use.

Services & Deliverables

Everything you need — built, delivered, and ready to run.

🏗️

n8n Workflow Architecture & Build

  • End-to-end pipeline design: data flow mapping and failure-point analysis before any node is written
  • Custom JavaScript Code nodes for parsing, enriching, validating, and routing data
  • Multi-workflow orchestration with webhook architecture and self-hosted deployment patterns
  • Exported JSON with all credentials stored as environment variables — nothing hardcoded
🧠

AI Model Integration & LLM Orchestration

  • OpenAI, Anthropic Claude, Gemini, Groq, or OpenRouter — called cleanly inside workflow nodes
  • Structured prompt engineering that returns consistent, parseable JSON outputs every time
  • n8n 2.0 AI agent nodes and LangChain integration for agentic decision-making loops
  • RAG pipeline setup with Pinecone or Weaviate for context-aware AI processing
🔌

API & Platform Integrations

  • HubSpot or Pipedrive: custom properties, deal pipelines, API-based record creation and updates
  • Slack, Gmail, Apollo.io, Airtable, Notion, Google Workspace — OAuth 2.0 and REST/GraphQL
  • Rate limit handling, pagination, and custom HTTP request design across all platforms
  • GDPR-compliant data pipelines with consent gates and responsible personal data handling
🛡️

Error Handling, Logging & Documentation

  • Every step has a failure path: graceful degradation, automatic retry, contextual error logging
  • Alerts routed to the right person with recommended actions — not just raw error codes
  • Full error handling map showing exactly what happens at every possible failure point
  • Plain-English workflow explanation so any non-technical stakeholder can understand and maintain it

How We Get There

A clear, phased approach so you always know what's next.

1
Discovery & Architecture Days 1–2

Deep dive into your business processes, data flows, and platform stack. Map the full automation architecture on paper — nodes, branches, failure paths, and approval gates — before a single workflow node is written.

2
Core Workflow Build Days 3–7

Build the primary n8n pipelines: API integrations, data transformation nodes, webhook triggers, and CRM record management. Test with realistic production-grade data at every stage.

3
AI Integration & Error Handling Days 8–10

Wire in LLM calls with structured output prompts, human-in-the-loop approval gates, and full error handling — retry logic, contextual logging, and routed alerts. Validate AI outputs against downstream node requirements.

4
Documentation & Handoff Days 11–12

Deliver the full package: exported workflow JSON, environment variable credential setup, error handling map, and a plain-English stakeholder walkthrough. Everything your team needs to maintain and extend the system independently.
