Retail Knowledge Graph In this project, we built a semantic knowledge graph tailored to the retail industry. The pipeline involved developing AI agents to transform heterogeneous data into standardized formats. Ontologies were created to represent domain knowledge accurately. Using Gemini models and LangChain, user queries were converted into Cypher queries to retrieve insights from a Neo4j database. We utilized an MCP server for orchestration and LangSmith for secure login and audit trails. This system enhances complex data exploration for non-technical users.

Prompt Engineering Mini-Academy is a digital learning product built using Kajabi. It helps users learn how to write better AI prompts and use AI tools for daily tasks such as writing, research, summarization, and productivity. The problem it solves is that many people use AI tools without a proper structure, which leads to weak or generic results. This product gives users a clear learning path, practical prompt templates, and workflow examples to improve the quality of their AI outputs. I used Kajabi to create the landing page, email capture form, downloadable prompt resource, product offer, checkout page, and course structure. A sample video is attached to demonstrate the product flow and user experience.

Cover image for Al-Insaan Care: A Supportive App
Al-Insaan Care: A Supportive App for Illiterate Needy People Al-Insaan Care is a mobile application specifically designed to bridge the accessibility gap for illiterate and needy individuals. By removing traditional text-based barriers, the platform empowers users to request and receive essential financial aid and material donations—including food, clothing, electronics, and blood—with dignity and ease. Project Overview The primary goal of Al-Insaan Care is to provide an inclusive, user-friendly experience for populations that struggle with literacy. The application leverages multimedia tools to ensure that navigating the path to assistance is as intuitive as possible. Key Features Accessibility-First Design: Information is presented through visuals, audio instructions, and videos rather than text. Voice-Activated Requests: Users can submit vital information (CNIC, address, house details) via voice messages or direct calls. Thorough Verification: An administrative department validates all requests to ensure aid reaches those truly in need. Streamlined Distribution: Integrated delivery services handle the distribution of material goods, while money and blood are managed through direct channels. Social & Community Engagement: A social feed allows for community interaction and updates on humanitarian efforts. UI & User Experience The interface is designed to be clean and minimalist, focusing on high-contrast iconography and simple workflows. Main Components Section AND Description Donation Portal: Uses icons (cutlery for food, shirt for clothing, etc.) to help users identify categories without reading. Checkout Flow: A simple process with a 100% discount model for needy recipients, resulting in a total cost of Rs.0. Dashboard: Provides administrators and donors with a visual overview of contributions and user growth through line graphs. Chat Interface: Includes a microphone option for instant voice commands and communication with support staff. Activity Feed: Tracks real-time user interactions, likes, and comments to foster a supportive community. How It Works Request: A user in need accesses the app and submits their details using voice commands or multimedia tools. Verify: The administrative team reviews the voice-submitted data and validates the request. Fulfill: Donors or the organization provide the requested items. Deliver: The delivery department ensures the items reach the verified address via courier or direct distribution.
