Learning Path – Step‑by‑Step
1. Kick-off & Mindset
Resource | Description | Action |
|---|---|---|
▶️ Kick-off Video | Production‑grade mindset, goal‑setting, success‑metric definitions and the mindset shift from “prototype works” → “system survives traffic”. | |
📄 Engineering Canvas PDF | Worksheet to define reliability, security, observability and lead‑gen KPIs | |
✅ Metrics Checklist | Checklist of % leads captured, fallback‑rate, MTTR, observability coverage |
2. Tool Foundations

4. Project 2: Enhanced Automation Workflow
Resource | Description | Action |
|---|---|---|
▶️ Automation Overview | Build a lead‑capture pipeline with validation, de‑duplication, dead‑letter queue and optional enrichment. | |
📂 n8n Workflow Template | Tally webhook → Validate → De‑duplicate → Enrich (Node.js) → NocoDB insert → Alert (Slack/Email) | |
📂 Enrichment Service | Simple Node.js function ( | |
📂 Dead-Letter & Alert Repo | n8n sub‑workflow that writes failures to | |
📄 Run Book | Operational guide covering webhook validation, rate‑limiting, DLQ handling and manual retry procedures |

Who Is This For?
No-Code Builders
Implement the safety net of fallbacks, monitoring dashboards and security without writing a line of code.
Code-first Devs
Utilize drag‑and‑drop speed, then dive into custom APIs (FastAPI / Node.js) for email, validation or advanced guardrails.
Full-stack & Ops
Implement observability, audit trails and SLA‑ready alerting with Grafana Cloud and Prometheus.
Product Leaders & Founders
Build a trustworthy AI sales‑assistant that captures leads, validates data and reliably notifies the sales team.
What You'll Achieve
- A production‑grade AI Agent that captures leads, stores in a Database and emails prospects in real time.
- Reliability & fallback – Automatic retry, circuit‑breaker and dead‑letter queue so a single failure never drops a lead.
- Full observability from day 1 via Prometheus counters and Grafana Cloud dashboards.
- Secure data handling using API‑key‑protected webhooks, NocoDB role‑based write rules and prompt‑injection detection.
- An end-to-end automation pipeline – Tally → n8n → NocoDB) with validation, de‑duplication, dead‑letter queue and optional enrichment.
- Ready-to-run code (FastAPI, Node.js, Flowise flows, n8n templates) that you can swap for self‑hosted services later.
