I will build custom ai agents, rag chatbots, and vapi voice call agents
Muhammad Uzair
About this gig
Ready to automate your business with AI?
I'm a full stack AI engineer building real, production grade AI agents, not simple prompt wrappers. I combine backend engineering with modern AI tools to build voice agents, RAG chatbots, and lead generation systems that businesses actually run on.
What I build
Voice and call agents using Vapi and Twilio that sound human, handle inbound and outbound calls, and book appointments. RAG chatbots trained on your own docs and data with accurate, source grounded answers and zero hallucination focus. Lead generation agents that qualify leads and update your CRM automatically. Custom multi agent systems that take real actions like booking meetings and triggering workflows.
Tools I use
OpenAI, LangChain, Vapi, Retell, Pinecone, Supabase, Node.js, NestJS, PostgreSQL, n8n, HubSpot, and more.
Why choose me?
I build the complete system, not just a prompt. Real RAG architecture with source grounded answers. Direct CRM and calendar integrations. Clean, documented, fully owned source code. Honest scoping call before you order.
Message me your use case and let's build your agent today.

I'm a full stack engineer specializing in AI agents, n8n automation, and SaaS development for startups and growing businesses.
I build custom AI agents, RAG chatbots, and voice agents, along with n8n workflows that remove manual work. I also build SaaS products, admin dashboards, and backend systems using Next.js, Node.js, and PostgreSQL.
I build complete, working systems, not shortcuts, with clean documented code and full ownership on delivery. I start every project with a scoping call so you know what to expect.
Message me your project and I will map out the best way to get it done.
My Portfolio
FAQ
Can you build a voice agent using Vapi that sounds natural?
A: Yes — I build inbound/outbound voice agents on Vapi (or Retell AI/Twilio) with natural voice synthesis via ElevenLabs, including real-time human call transfer.
Can the agent qualify and score leads automatically?
Yes — I build lead qualification logic directly into the agent, with auto-sync to your CRM (HubSpot, GoHighLevel, Airtable, etc.) and lead scoring rules.
Will the chatbot hallucinate or give wrong answers?
No — I build proper RAG pipelines (embeddings + vector search) so answers are grounded in your actual data with source citations, not guessed.
Do I need my own OpenAI/Vapi API key?
Yes, you'll provide your own API keys (OpenAI, Vapi, Twilio, etc.) so you retain full control of usage, costs, and data privacy.
Can this connect to our existing database or CRM?
Yes — PostgreSQL, MongoDB, Supabase, HubSpot, GoHighLevel, Airtable, Notion, and most tools with an API are supported.
Do you offer ongoing support after delivery?
Yes — every package includes support days, and a monthly maintenance/optimization retainer is available as an extra.
Can I request a custom multi-agent system not listed in packages?
Absolutely — message me your requirements and I'll send a custom quote.
