Build AI-Powered CRM Lead Qualification Automation (Telegram + Google Sheets + Gemini)

We're looking for an automation developer to build a production-ready AI-powered lead qualification workflow using Telegram, Google Sheets, and Gemini AI. Potential customers will interact with our Telegram bot, which should conduct a structured conversation by asking one question at a time to collect information such as name, company, budget, business type, timeline, and project requirements. The workflow should validate user inputs, maintain conversation state across multiple messages, dynamically adjust follow-up questions, and evaluate the quality of each lead using Gemini AI. Every interaction must be logged into Google Sheets, and qualified leads should automatically trigger notifications to our sales team. The workflow should be implemented using a node-based automation platform (n8n, Activepieces, Make, etc.) with custom JavaScript where necessary.
