AI Expert for Lead Intake, Scheduling, Payment and CRM integration.
Hamza took our lead intake, scheduling, payments, and CRM, systems that weren't talking to each other, and turned them into one system that actually runs itself. He didn't need hand-holding, asked the right questions upfront, and just got it done. This is exactly the kind of person you want on a project like this. The team is very solution oriented, as well as Customer Idea oriented. Meaning, they are good at taking action on ideas I had, presenting options, adjusting the options to my satisfaction, and being patient all the while. Great group! I would highly recommend.

Build Complete Business Automation System - AI Phone Agent + GPS Tracking + Scheduling
We hired Hamza and his team to build a complete AI automation system for our business and the results have been outstanding. They built a full job scheduling and automation system that runs our operations end to end. The AI phone agent handles calls and bookings on its own, which has saved us hours every week. GPS tracking is built right into the platform so we can see everything in real time, along with automated scheduling and weather checking built into the workflow. The entire system works seamlessly and has genuinely transformed how we run day to day operations. Communication was excellent throughout the project and Hamza's team delivered exactly what we needed on time. Highly recommend Hamza for anyone looking to build custom AI systems, automation tools, or AI agents for their business

AI Workflow Automation Expert for Dental Business
I hired Hamza for a consultation on building an AI-based system for dental practices, covering call handling, appointment scheduling, patient follow-ups, and no-show reduction. He put together detailed documentation and a full roadmap for how the system should be built, along with his recommendations on making it something i could actually sell to dental clients. His experience in Ai automation was clear from how thorough the consultation was. I'm now moving forward with him to build the full product based on what came out of that session. Would recommend if you need someone who actually knows how to scope an Ai project, not just talk about it.

Medical Weight Loss Clinic system devlopment
Hamza and Stack up team built our entire weight loss platform from scratch including patient intake, BMI checks, prescription approval system - the whole thing. The also added some AI automation that's honestly saved us so much manual work on the backend.
Hamza and his team was easy to reach whenever we needed him and always understood exactly what we were trying to build even when we couldn't explain it well ourselves. We would work with them again in a heart beat, great team.

Job Success
Lahore, Pakistan - 10:33 am local time
10+ years building web and AI applications. Top Rated Plus with a 100% Job Success Score. Recent work includes a roofing AI system that recovers missed calls within seconds, a landlord compliance SaaS for Baltimore City, and a legal document abstraction engine using Claude and Azure Document Intelligence.
What I build:
AI Agents and Custom Automation
I design AI agents, multi-agent workflows, and custom business process automation that handle real operations end to end: lead qualification, follow-up, document processing, customer support triage, and internal ops. Built with custom code and API integrations (webhooks, REST, third-party platforms), with human-in-the-loop approval where it matters, using OpenAI and Claude. I architect these as clean, maintainable systems, not brittle scripts.
Full-Stack SaaS and MVPs
I take validated ideas to working, multi-tenant SaaS products: user accounts, dashboards, admin panels, role-based access, subscriptions, and reporting. Stack: Next.js, React, Node.js, Nest.js, Python, FastAPI, Supabase, PostgreSQL, Stripe, and cloud deployment on AWS and GCP. Milestone-based delivery with a working build at every checkpoint.
RAG and LLM Applications
I build retrieval-augmented generation (RAG) systems and document intelligence pipelines: chat-with-your-documents, knowledge bases, structured extraction, and grounded, no-hallucination outputs. Using LangChain, Pinecone, Chroma, vector embeddings, prompt engineering, and contextual memory across GPT-4, Claude, Llama, and others.
CRM and Lead Management Systems
I build AI-driven lead management and CRM platforms: multi-source lead intake, AI lead scoring and qualification, automated follow-up sequences, pipeline tracking, and conversion reporting in a single dashboard.
Voice and Conversational AI
I build conversational and voice agents using Deepgram and Whisper (speech-to-text), ElevenLabs (text-to-speech), and Twilio and SignalWire for real-time call and IVR workflows.
Core skills:

Why work with me:
