About this service

Summary

I build custom AI agents powered by LangChain and LangGraph, tailored to automate workflows, integrate with your data sources, and deliver reliable, intelligent interactions. What makes my work unique is a focus on production-ready design—from scalable architecture and seamless API integrations to clear documentation and training—so you get not just an AI prototype, but a fully deployable solution that drives real business value.

What's included

  • Requirements & Use-Case Analysis Report

    Document outlining business needs, workflows, and how AI agents will fit in.

  • System Architecture & Design

    1. High-level architecture diagram showing LangChain, LangGraph, APIs, databases, and integrations. 2. Technical documentation explaining the design choices.

Mr. Daniyal Afaqi built the website for our company Helping Hands Health Care Ltd (https://helpinghandhealthcare.org) in React.js. He created the design of the website, coded it, and also did all of the revisions, that I felt were required. He did a good job and I would recommend him for your project as well. Thank you Daniyal.

Mr. Daniyal Afaqi was given two web development tasks: redesigning our company's website ( https://svdp.org.pk ) and designing an MIS ( management information system ) to manage the company's daily business activities. He completed both projects successfully on time and delivered a good final product. Thank you Daniyal
