You will get a custom AI receptionist, lead qualifier, or support voice agent
Project details
You will get a custom AI voice agent built for your specific use case - receptionist, lead qualifier, customer support, or appointment booking - with sub-1-second response time so conversations feel natural, not robotic.
WHY ME
I have a live, working demo you can talk to right now at callflow-demo.vercel.app. Three named voice agents (dental receptionist, real-estate lead qualifier, customer support) running at ~1.0 second speech-to-speech round-trip. Almost no other voice-AI seller on Upwork has a public live demo.
I work on dual stacks - OpenAI Realtime API for fastest launch, and self-hosted Hugging Face stacks (Whisper, wav2vec2, custom STT/TTS) when you need cost control or data sovereignty. I will tell you upfront which fits your business and never lock you into one tool.
I am an AI engineer with production experience: shipped LLM agents and voice systems at scale, including the first production conversational LLM agent for a national-scale e-ticketing platform. You get full source code, deployment guide, and documentation. No black boxes.

About Nouman
AI Engineer | RAG, Voice Agents & Vision Systems That Ship
100%
Job Success
Lahore, Pakistan - 8:46 am local time
You need AI that ships, stays on budget, and becomes a reliable part of your product.
I’m an AI Engineer with 5+ years of experience building production-ready AI systems across RAG, voice agents, computer vision, document intelligence, and recommendation systems. I build AI as accountable, measurable software — not magic you hope behaves.
I have worked as Lead AI Engineer for Bookme.pk and Bookme.sa, where I shipped recommendation systems, document extractors, and intelligent travel-guide agents used by real customers at scale.
Recent AI Projects
CallFlow — Real-Time Voice AI Agents
Built a production-style voice AI demo platform with 3 live business agents:
• AI Receptionist for appointment booking and rescheduling
• AI Lead Qualifier for real estate lead qualification
• AI Customer Support agent for order inquiries, returns, and product questions
The system is designed around real-time voice interaction with sub-second response behavior, browser-based calling, and integration-ready workflows for CRMs, calendars, knowledge bases, APIs, Twilio, WhatsApp, and web channels.
OmniSight — AI Video Monitoring System
Built an AI-assisted surveillance and monitoring system where users can describe what they want to detect in plain English.
Example rules include:
• “Person in restricted area after 6pm”
• “Vehicle blocking the emergency exit”
• “Unattended object near entrance”
The system processes webcam/video input, evaluates frames with AI vision, detects rule matches, and returns alert-ready visual evidence. This is useful for security monitoring, safety compliance, retail operations, and industrial inspection workflows.
Quill — AI Writing Workspace
Built a Notion-style AI writing editor where AI is embedded directly into the writing flow instead of forcing users to switch tabs.
Key features include:
• AI autocomplete using inline “++” commands
• In-place rewriting and grammar improvement
• Shorten, expand, and improve selected text
• 12+ editor block types
• Markdown support
• Rich content embeds
• Dark mode
This project demonstrates how I build AI features that feel native inside a product rather than bolted on as a chatbot.
Tickline — Financial Filing RAG Assistant
Built a financial RAG system for question-answering over 10-K style filing data.
The assistant is grounded across 5 major filing sections, including:
• Business Overview
• Risk Factors
• MD&A
• Financial Statements
• Segment Reporting
It answers financial questions with cited source sections and exact supporting excerpts, reducing hallucinations and making the output easier to verify.
Bookme.sa Intelligent Travel Guide
Built an intelligent travel-guide agent grounded in real inventory rather than generic AI knowledge. The goal was to help users get accurate, useful recommendations while keeping inference cost predictable and scalable.
What I Can Help You Build
• RAG systems and knowledge assistants
• AI chatbots and agentic workflows
• Voice AI agents and real-time conversational interfaces
• AI document editors and writing tools
• Computer vision and video monitoring systems
• OCR and document extraction pipelines
• Financial, legal, healthcare, or internal-document Q&A systems
• Recommendation engines
• AI prototypes that can actually become production features
How I Work
I don’t start by drowning you in meetings or vague AI strategy documents.
I work in short, practical sprints:
1. Understand the use case and success criteria
2. Build a working prototype quickly
3. Test it against real examples
4. Measure quality, latency, and cost
5. Improve until it is ready for production
You see something real early, give feedback on an actual product, and we refine from there.
Why Clients Hire Me
• 5+ years of hands-on AI/ML engineering experience
• Production experience, not just notebooks and demos
• Strong focus on cost control and scalable architecture
• Experience with RAG, voice AI, computer vision, OCR, and recommendation systems
• Ability to turn vague AI ideas into clear, testable product features
• Comfortable building end-to-end: backend, AI pipeline, APIs, deployment, and evaluation

If you have an AI use case, send me a message. I’ll tell you honestly whether AI is the right fit, what I would prototype first, and how to avoid wasting budget on a system that looks good in a demo but fails in production.
