Haroon Jawad

I'm a Senior Full Stack Engineer and AI Applications Developer with deep experience in building scalable web platforms and intelligent systems. My work spans both ends of the stack—React, Node.js, MongoDB, and SQL—as well as advanced AI/ML integrations using OpenAI, LangChain, LangGraph, and Retrieval-Augmented Generation (RAG).

In addition to full stack development, I specialize in building agentic AI systems—autonomous agents that reason, plan, and take action using tools like CrewAI and structured reasoning pipelines. Whether it’s deploying LLM-powered assistants, integrating AI into real-world workflows, or creating robust APIs around intelligent features, I bring both technical execution and strategic thinking to every project.

I've delivered projects for startups, healthcare platforms, ML-integrated ID verification tools, and analytics dashboards. I’m also a Top Rated Plus developer on Upwork, where I help global clients bring their technical visions to life.

There are a million people out there who know how to code. Not everybody knows how to listen to your needs, follow up with you promptly, meet deadlines, or talk about your website in a way that's not filled with technical jargon. In addition to these, I strive to be open, friendly, easy, and fun to work with!
