Project details
I build Retrieval-Augmented Generation (RAG) AI assistants that allow your team or customers to interact with PDFs, Word documents, websites, Notion, Confluence, databases, knowledge bases, and other business content using natural language. Instead of relying solely on a large language model, your AI assistant retrieves information from your own data, providing more accurate, reliable, and up-to-date responses.
Whether you need an internal knowledge assistant, customer support chatbot, document search system, employee assistant, legal document assistant, healthcare knowledge base, or AI-powered business assistant, I'll build a secure and scalable solution tailored to your business.
What You'll Get
✔ Custom RAG AI Assistant
✔ OpenAI, Claude & Gemini Integration
✔ LangChain / LangGraph Development
✔ Vector Database Integration (Pinecone, Weaviate, ChromaDB)
✔ Intelligent Document Processing
✔ Semantic Search & Embeddings
✔ PDF, Word & Website Knowledge Base
✔ Secure Authentication & User Access
✔ API Integration
✔ Production-Ready Source Code
✔ Documentation
✔ 2 Months Post-Launch Support

Help automating front desk tasks in healthcare clinics using AI
I recently hired Shahbaz for a pretty big project, and he absolutely exceeded my expectations. From the very first conversation, it was clear how knowledgeable he is in his field—he offered insightful suggestions and solutions that showed real expertise.
What stood out most was his professionalism and patience. He explained everything clearly, never rushed me when I had questions, and guided me step-by-step through decisions I wasn’t sure about. He was always responsive, one step ahead, kept me updated, and hit every target and milestone either on time or early.
Thanks to his excellent work and great communication, the project turned out even better than I had hoped. I will be working with him on future projects, and I highly recommend Shahbaz to anyone looking for top-tier, reliable talent. I am so blessed to have found him!

Job Success
Lahore, Pakistan - 10:36 am local time
I’m a Full Stack Developer focused on building and improving production software across AI applications, SaaS platforms, CRM/automation systems, healthcare workflows, marketplaces, and custom business applications.
Over the last 8 years, I’ve worked across the full product lifecycle, from understanding an existing system and finding what is actually broken, to designing the backend, building the frontend, integrating AI/third-party services, and taking the product toward a reliable production implementation.
What I work on
• AI-powered applications and workflow automation
• AI receptionists, voice agents, GPT and telephony integrations
• SaaS platforms and multi-tenant business applications
• CRM, ERP and operational automation
• Custom web applications and internal business systems
• REST APIs, backend architecture and third-party integrations
• React / Next.js frontends and Node.js backends
• PostgreSQL, Redis, Docker and cloud infrastructure
• Existing application upgrades, integrations and performance improvements
• MVP development and production-ready product builds
Recent Upwork work
I’ve completed projects involving:
• AI receptionist / missed-call lead capture for UK garages
• AI automation for healthcare clinic front-desk workflows
• AI application development based on an existing product plan
• AI/ML model development and rapid prototyping
• GoHighLevel white-label CRM and AI automation
• Smart AI call-center development with GPT and voice APIs
• React + Node.js SaaS development
• Full-stack development and upgrades for a freight marketplace
I’m also currently working on SaaS, CRM automation, payroll/commission management, and blockchain-related software projects.
How I approach projects
I don’t start by blindly writing code.
First I understand the product, existing architecture, business workflow, integrations, data flow, and constraints. Then I determine what should be changed, what should remain stable, and how the implementation should be structured so the result is maintainable rather than becoming another layer of technical debt.
Depending on the project, I can work across:
✔ Frontend: React, Next.js
✔ Backend: Node.js, NestJS, Python.
✔ Data: PostgreSQL, Redis
✔ Infrastructure: Docker, AWS / Google Cloud
✔ Integrations: REST APIs, Stripe, OAuth, telephony/SMS, third-party services
✔ AI: LLM integrations, AI automation, conversational AI, voice workflows
If you already have an application, I can work with the existing architecture rather than forcing a rewrite.
If you're starting from an idea or MVP, I can help turn the requirements into a practical technical implementation.
If you're dealing with an existing system that works but needs upgrades, integrations, automation, or architectural improvements, that's also where I can add significant value.
My goal is simple: build software that works today and gives you a solid foundation for what comes next.
