AI Agent Expert Needed for Consultation to Automate Online Shopping Store
Working with Mohsin was a great experience. He clearly explained how AI agents can automate my online shopping store and provided a practical, step-by-step strategy for post-order automation, customer follow-ups, and workflow optimization. His knowledge of AI and automation is impressive, and he communicates in a very clear and professional way. I highly recommend him for AI and eCommerce automation projects.

Job Success
Lahore, Pakistan - 11:08 am local time
Over the past 4 years, I have helped businesses launch SaaS platforms, automate their workflows, and add AI that actually works in production not just in a demo. I handle everything: the React frontend your users see, the Node.js or FastAPI backend that powers it, and the AI logic that makes it smart.
Here's what I have shipped for clients on Upwork:
➤ AI chatbot for an e-commerce store that handled customer queries around the clock
➤ Automation agent for an online retailer that cut manual processing by 60%
➤ Shopify bot and full-stack web apps for growing businesses
𝗪𝗵𝗮𝘁 𝗜 𝗕𝘂𝗶𝗹𝗱
➤ Full-stack SaaS platforms: React, Next.js, TypeScript, Node.js, FastAPI
➤ AI chatbots and virtual assistants: GPT-4, Claude, Gemini APIs
➤ LangChain and LlamaIndex agents with memory, tool use, and prompt engineering
➤ RAG systems — document Q&A, knowledge bases, AI-powered search
➤ REST API design, third-party API integrations, and Stripe payment setup
➤ Workflow automations: n8n, Make, Zapier
➤ Authentication systems, role-based access, and secure backend architecture
