Summary

I design, build, and maintain production n8n workflows through Meerkat LLC, my automation consultancy — currently 137 workflows running in production (n8n Cloud + self-managed). Focus areas: Claude (Anthropic) API integrations, voice AI (Vapi + ElevenLabs), and CRM lead-gen pipelines. Error handling, monitoring, and documentation are treated as first-class deliverables: every client-facing workflow ships with a global error handler, alerting, automated backups, and a written runbook.

Selected production work

AI Quoting Agent — Claude + n8n, multilingual (DE/FR/IT/EN/ES)

Built to a Swiss plumbing/HVAC company's spec · live on n8n Cloud · case study

Free-text intervention requests → Claude extracts line items (the LLM never touches prices) → exact supplier-catalog matching only → deterministic pricing (margins, labor, travel, 8.1% Swiss VAT) → branded PDF quote in the customer's language.
Live-tested July 2026: German request returned a correct CHF 8'555.90 quote in seconds; a made-up product was flagged for human review instead of priced — zero hallucinated SKUs by architecture.

CRM Lead-Gen Pipeline — Claude-powered triage, scoring & enrichment

Runs in production on Meerkat's own inbound flow · case study

Webhook capture → Claude intent classification (hot/nurture/spam/support) with versioned, few-shot prompt templates → enrichment → deduplicated CRM upsert → owner routing with AI summaries in Slack.
Guardrails throughout: confidence thresholds to manual review, timeout/retry/token-cost logging on every LLM call, dead-letter queue with alerting — no lead silently dropped.

Voice AI Qualification Agent — Vapi + ElevenLabs + n8n

24/7 answering, qualification & booking · case study with live demo recording

End-of-call webhook (signature-validated) → Claude extracts structured fields into a strict JSON schema with validation-and-retry → deduplicated CRM upsert → automated SMS/email follow-up within minutes of hang-up.

Global Error Monitoring & Self-Recovery Harness

Deployed on every client instance

Central Error Trigger catches every failed execution — logs workflow, node, error, and execution URL; transient errors auto-retry with backoff; hard failures alert immediately; weekly reliability digest.

Remote n8n Job Hunter — Multi-Board Scraper & AI Scorer

Self-built, runs unattended daily in production · productized for sale

Scheduled scrape of three job boards → dedupe against history → LLM scores each lead 0–10 with reasons → Google Sheets append + email digest. Packaged and QC-audited for marketplace sale.

How I work

Documentation: annotated canvases, written runbooks (purpose, credentials, failure modes, recovery), walkthrough videos.
Reliability: global error trigger + per-node retry + dead-letter branches as standard on every build.
Maintainability: descriptive node naming, reusable sub-workflows, environment-separated credentials, staged rollouts.
Communication: US-based, async-friendly, written updates at each milestone. Available 6am–12pm US Central, every weekday.
