A lead fills out a form on your website. What happens in the next 5 minutes
decides whether they become a customer — or forget you exist.
THE PROBLEM
Leads sit in a mailbox or a spreadsheet until someone notices them. By then,
78% of buyers have already contacted a competitor.
THE SOLUTION
Lead Machine — an n8n pipeline that handles every inbound lead automatically,
from form submission to follow-up email in about 30 seconds, 24/7:
webhook → validation → duplicate check → Google Sheets → welcome email
→ Telegram alert to the manager → automatic follow-up in 24h
Every step is plain n8n nodes: no AI keys, no token fees, no monthly SaaS.
Validation rules, email texts, follow-up delay — all editable in the n8n UI.
It runs on YOUR infrastructure: credentials stay with you.
Explanation: Delivered a production-ready SaaS analytics MVP dashboard for a startup. My responsibilities included frontend development using Next.js 14 and Tailwind CSS, backend architecture with Supabase Auth & DB, and integrating realtime data streaming (WebSocket) for dynamic charts. Reduced the standard development sprint from 6 weeks to 3 weeks, resulting in the client securing initial user feedback 50% faster than their internal roadmap anticipated. This highlights speed and scalability for early-stage ventures.
