Project details
Echo is a frontend demo of an AI voice agent that turns inbound phone calls into CRM leads. A caller dials a business number, a Vapi or Retell agent answers, qualifies them, and the lead is pushed to GoHighLevel or Zoho CRM. It's built as a sellable $50 Upwork catalog MVP: a polished dashboard driven by simulated data, plus a full blueprint for building the real backend.
What was built
Screens:
Dashboard.
Live Call simulator.
Call Log and Call Detail.
Leads (drag-and-drop board and table).
Voice Agents.
Event Log.
Settings.
Live Call simulator:
It plays four scripted calls: new lead, pricing inquiry, escalation to a human, and a booking where the CRM push fails once and then retries.
Each call shows a streaming transcript, fields filling in live, sentiment and an AI summary.
Each call ends with a pipeline that pushes the lead to the CRM.
Login: static demo credentials . Sign-up is visual only.
Design: dark and light themes, responsive down to phone width.
Tech
Vite, React 18, TypeScript, Tailwind v4, Zustand, Recharts, Framer Motion and Lucide.
There is no backend. Everything goes through one file, so building the real backend later means swapping that file, with no page changes.

Problems I solve:
Leads going cold because follow-up takes too long. Sales conversations scattered across WhatsApp, Telegram, and a CRM that don't talk to each other. Repetitive qualification and booking work eating time that should go to closing deals.
What I build:
• AI sales agents and AI SDR-style qualification systems
• Lead qualification and lead routing workflows
• CRM automation and CRM integrations (GoHighLevel and others)
• AI chatbots for sales and support
• WhatsApp and Telegram automation
• Automated follow-up sequences
• Appointment and booking automation
• AI-powered business workflows
• API and webhook integrations
• SaaS platforms
• AI integrations using OpenAI and Claude APIs
Technical stack:
Node.js, Next.js, TypeScript, JavaScript, PHP, Laravel, CodeIgniter, React, PostgreSQL, MySQL, REST APIs, webhooks, Stripe, PayPal, AWS
Experience:
8+ years of full-stack software development, applying that engineering depth to AI and automation systems rather than building simple demos — I design for production reliability, not just proof-of-concept.
Selected work:
— WhatsApp AI Support & Lead Qualification Bot (n8n + OpenAI)
— CRM Lead Automation (n8n + GoHighLevel + AI Lead Scoring)
— Real Estate Lead Automation (n8n + AI Qualification + CRM)
— AI Telegram Lead Generation Platform
— WhatsApp Automation with Smart Replies, Campaigns & CRM
Why work with me:
Most automation freelancers can wire up a no-code tool. Fewer can also build and scale the backend systems those tools plug into — APIs, databases, queues, deployment — which is where automations tend to break under real usage. I bring both.
If manual lead follow-up or disconnected sales tools are costing you deals, let's talk about what's happening and how to fix it.
