Working with this developer was one of the smoothest collaboration experiences I've had on Upwork. Clear communication from day one, full ownership of the work, and always available when a bug needed fixing. I never had to chase him; no delays, no hand-holding needed.
What I appreciated most was that he didn't just write code, but he thought about the product. Proactive, reliable, and genuinely invested in getting things right. Wishing him all the best! Any team lucky enough to work with him on a React, Next.js, or Laravel project is in good hands :)

About Muhammad
AI Agent & Automation Developer | n8n | ChatGPT | Next.js | Laravel
Pindi Gheb, Pakistanย - 2:41 am local time
Because when automation breaks in production, your operations grind to a halt. When an AI agent gives wrong answers, you lose customer trust. When the developer disappears after delivery, you're left maintaining something nobody understands.
That is the problem I solve.
Over the past few years, I have built and deployed 50+ production workflows and AI-powered systems for founders and agencies across multiple industries. A WhatsApp AI assistant powered by Claude and Qdrant that answers questions from a private business knowledge base using RAG, handling real customer queries every day. Full n8n automation pipelines covering lead management, CRM sync, multi-channel messaging, invoice processing, and operational reporting, all running without human intervention. SaaS platforms built on Next.js and Laravel with subscription billing, multi-tenant architecture, admin dashboards, and payment integrations through Stripe and Razorpay. API integration layers connecting HubSpot, Twilio, WhatsApp Business API, Shopify, Google Workspace, and custom internal systems into unified, reliable pipelines. Self-hosted infrastructure on VPS with Docker, Nginx, PM2, and GitHub Actions, so what gets deployed actually stays up.
These are not demos or proof-of-concepts. These are production systems handling real business operations, real users, and real data every single day.
What I Build:
AI Agents & Integrations: Building AI systems that solve real business problems, not just prototypes that look good in a pitch. I have built WhatsApp AI assistants with RAG-based knowledge retrieval, integrated OpenAI, Claude, and Gemini into existing products, and automated support, operations, content generation, and internal processes using LLMs where they actually add value. If you need a custom AI agent, knowledge assistant, or AI-powered workflow taken from idea to production, I can get it there.
n8n Automation & Workflow Development: I have built 50+ production workflows for businesses, including lead management, CRM automation, multi-channel messaging, invoice processing, reporting, notifications, and end-to-end operational automation. I self-host n8n, build complex multi-step workflows, and connect everything to third-party APIs, databases, CRMs, and internal systems. If a process is repetitive, it can almost certainly be automated.
SaaS & Full-Stack Development: Building scalable web applications using Next.js, React, Laravel, PHP, and Node.js, from subscription platforms and multi-tenant SaaS products to admin dashboards, REST APIs, custom CMS solutions, and payment integrations. I build systems that are maintainable, scalable, and ready for real traffic, not just the first hundred users.
API Integrations & Webhooks: I have integrated HubSpot, Stripe, Razorpay, Twilio, WhatsApp Business API, Google Workspace, Shopify, WooCommerce, and dozens of custom APIs. Whether you need a new integration built from scratch or want existing systems to finally talk to each other properly, I handle the full implementation end-to-end.
Infrastructure & Deployment: Shipping code is only half the job. I manage deployments and infrastructure using Docker, GitHub Actions, VPS, Nginx, PM2, MySQL, and PostgreSQL. What I build gets deployed properly, monitored, and documented so it can be maintained long after launch without calling me for every small fix.
