Project details
Looking to build your own ChatGPT-style AI web app with authentication and chat history? 🚀
I will design and develop a full-stack AI-powered web application tailored to your business needs. Built with React + Flask, it delivers a seamless ChatGPT-like interface where users can sign up, log in, and access their entire chat history, giving them a polished, professional AI experience.
Your AI web app can:
✅ Provide ChatGPT-like chat interface with memory
✅ Secure user authentication & account management
✅ Save and manage complete chat history
✅ Integrate OpenAI API with custom reasoning & memory workflows
✅ Scale into a SaaS product or enterprise-ready solution
✅ Support custom training, fine-tuning, and AI agents
Every app is built with scalability, reliability, and UX in mind. You get more than just a template, you get a production-ready AI product.
✨ What sets this project apart?
I don’t just build apps, I create custom AI agents and SaaS platforms designed to solve real problems. With 3+ years of experience and 100+ successful projects, I’ve helped businesses launch AI tools that go beyond chat, covering automation, customer support, and advanced AI workflows. 🌟

Job Success
Karachi, Pakistan - 11:35 am local time
My enterprise work lives on national-scale, policy-constrained platforms: multilingual AI assistants serving the public, multi-tenant RAG infrastructure, and agentic systems that execute real actions under role-based controls. That work sets my standards — source-grounded answers, policy guardrails, audit trails, tenant isolation.
WHAT I'M BEST AT
• Agentic AI that acts — LangGraph/CrewAI multi-agent systems with tool use, approval gates, and audit trails (MCP, A2A)
• Secure RAG for sensitive knowledge — hybrid retrieval, guardrails, RBAC, isolated vector stores
• Chat commerce & voice — WhatsApp ordering and booking systems with in-chat payments; voice agents that answer every call, 24/7
PROOF
• 100+ AI products delivered for 50+ businesses since 2023
• Products shipped in 4 languages — English, German, Hebrew, and Arabic-domain systems
• Google Cloud Certified — Associate Cloud Engineer
• Clients across 12 countries
RECENT BUILDS
Full case studies in my portfolio section below: an AI-powered diamond marketplace with seller and admin workspaces and a personalized showroom, a WhatsApp commerce bot with cart, location, and in-chat payment integration, AIventaX HR — a pluggable multi-agent HR assistant with orchestration, AI voice agents handling business calls end to end, and Instagram automation covering human-like comment replies and DM setting.
HOW I WORK
Scoped MVP first, or straight to a phased enterprise build — either way you get architecture that survives scale, and I stay accountable for it.
Building with AI — from a first WhatsApp bot to a compliance-heavy platform? Send an invite and tell me what you're trying to ship. I'll reply with a concrete approach, not a template.
