You will get Agentic AI Developer | LangChain, LangGraph, RAG & Multi-Agent Systems
Project details
I build production-ready agentic AI systems that think, plan, and act autonomously — helping businesses automate complex workflows and unlock real operational value.
With 4+ years of full-stack development experience and deep expertise in agentic frameworks, I specialize in designing and deploying intelligent systems using LangChain, LangGraph, CrewAI, and MCP. From single-task AI agents to sophisticated multi-agent orchestration with RAG pipelines, memory, and tool calling — I deliver solutions that are scalable, maintainable, and built for the real world.
What sets me apart is the combination of strong software engineering foundations with cutting-edge AI expertise. I don't just prototype — I build systems that are tested, documented, and deployed to production environments on AWS and modern cloud platforms.
Whether you're a startup looking to automate operations or an enterprise scaling intelligent workflows — I'll architect and deliver a solution precisely tailored to your needs.

Build an AI-Powered Tax Filing Lawyer Assistant Using LangGraph (Multi-Agent RAG System)
Working with Abdullah Salman on the AI-Powered Tax Filing Lawyer Assistant was an outstanding experience. He demonstrated exceptional technical depth in architecting the multi-agent RAG system using LangGraph, building a robust Python FastAPI backend, and seamlessly integrating complex AI workflows with a polished, production-grade Next.js frontend. His attention to detail — from intelligent agent orchestration to a clean, intuitive UI — truly set this project apart. I would highly recommend him for any advanced AI or full-stack project.
