AI Workflow Automation Expert
I own a service-based company and finding the right technical partner is not something that happens often. Hamza and the Stackup team are the real deal. They came in, understood how our business operates, and built everything around that. Custom CRM, automations, AI voice agents, conversational AI, the whole system was designed around our specific workflows. What stood out the most was how Hamza shows up. He does not just deliver and disappear. He is invested in where the product ends up and that comes through in everything he does. Communication was consistent, deliveries were clean, and nothing was left undocumented. We are mid-way through Phase 2 right now and have no intention of going anywhere else. Highly recommend.

Build a Direct Booking Website with PMS Integration, Guest Screening and Stripe Payment
Their team was reliable, communicative, and easy to work with throughout the project. They successfully handled the Guesty PMS integration with Airbnb and helped build a more scalable and organized short-term rental system with solid automation workflows. Strong technical knowledge, good follow-through, and professional project management overall. I’d recommend them for platform development, API integration, and operational system improvements.

Voyant: Cultural Tips MVP
Working with Hamza and his team at Stackup Solutions was one of the best decisions we made for this project. They delivered a fully functional cultural tips MVP that brought our vision to life faster than we imagined, intuitive, polished, and ready for real users from day one.
Hamza's AI expertise is genuinely impressive. He didn't just build an app. He engineered an intelligent, scalable solution that understood the product goal at its core and delivered results that went far beyond our expectations. The AI integration felt seamless, the UX flowed naturally, and the overall quality of the build was outstanding.
Communication was smooth throughout. Hamza's team was proactive, responsive, and consistently solution-oriented. They kept us aligned at every milestone and delivered on time without exception.
If you are looking for an AI development expert who combines deep technical skill with real product thinking to build intelligent applications that launch fast and scale confidently.

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.

Why work with me:
