I built a lead generation system in n8n that finds and verifies thousands of business emails in seconds.

Here's the full flow:

It scrapes every agency in any city you target. Extracts their website URLs. Filters out any fake or dead sites. Scrapes each website individually to pull the email. Verifies the email actually exists. Then logs everything into a clean Google Sheets database ready for cold outreach.

One click. Thousands of verified leads. Zero manual work.

I made a full step by step video showing exactly how I built this and I'm giving away the entire blueprint for free.

Verification is the step most people skip, then their bounce rate torches the sending domain. What are you using for the verify pass?

Echo is a multi-tenant SaaS for AI customer support with realtime chat, an AI voice agent, and AI automation. I was the primary developer on the full build, frontend, backend, and the AI layer. The AI is the core. It runs OpenAI, Claude, Gemini, and Grok through one multi-model setup, so a client can switch providers without a rewrite. A RAG pipeline connected to a vector database grounds every answer in the client's own content, so the chatbot never returns generic output. VAPI powers the voice agent, so customers can speak to support on a live call. Each tenant gets its own AI agent built on its own documents. The stack is Next.js 15 and React 19 inside a Turborepo monorepo, with separate apps for the dashboard, the embeddable chat widget, and backend services. Realtime chat runs on Convex. Clerk handles auth. API keys are encrypted per tenant through AWS Secrets Manager, so no two clients share credentials or data. Launch day held 60 live conversations at once with zero dropped sessions. What the client gets: an AI chatbot and voice agent that answer from their own content, work across multiple LLM providers, and stay isolated and secure per tenant.:
