Hi again :) a recently graduated Software Engineer who enjoys building things and understanding how they work behind the scenes.
- I mainly work on the backend, but I'm comfortable building across the stack when a project requires it.
- I build REST APIs and web applications with ASP.NET Core and FastAPI.
- I work with PostgreSQL and other relational databases for application data.
- I use Angular and React when working on the frontend.
- I've also explored AI/RAG applications using Qdrant, T5, and LLM APIs.
- I'm interested in how software systems fit together, from the database and API to the frontend.

├──People-Link/code
→A full-stack social networking application built around REST APIs and real-time communication.
- Backend: ASP.NET Core Web API with PostgreSQL and Entity Framework Core
- Architecture: Repository and Unit of Work patterns with DTOs to separate application concerns
- Authentication: ASP.NET Core Identity for authentication and authorization
- Real-time: SignalR-based presence tracking and messaging
- Frontend: Angular application with profiles, media uploads, filtering, sorting, likes, and pagination
├──Document Inspector/
A document validation system that checks DOCX files against predefined templates while combining document processing with AI-powered analysis.
- Document validation: Uses OpenXML to verify headings, fonts, spacing, and layout at the document-structure level
- AI modules: Provides grammar and coherence checking through a FastAPI service
- RAG: Enables users to interact with document content using retrieval-based context
- Integration: Connects ASP.NET Core, FastAPI, Qdrant, MySQL, T5-based models, and external APIs
- Recognition: Selected for the FYP 26 Competition at COMSATS University Islamabad
├──Visitor Tracking System/
An internal visitor management system built during my Software Engineering internship for managing visitor registration and visits across multiple branches.
- Access control: Admin, Receptionist, and Branch Officer roles with role-specific permissions
- CNIC OCR: EasyOCR extracts visitor information and reduces manual data entry during registration
- Real-time dashboard: Server-Sent Events provide live visitor check-in and check-out updates
- Backend: FastAPI REST APIs with PostgreSQL for visitor and visit management
- Frontend: React and TypeScript with React Hook Form for registration and validation
├──RAG Chatbot/code
→A document question-answering application that uses Retrieval-Augmented Generation to produce answers grounded in uploaded PDF content.
- Chunking: Splits documents into overlapping, sentence-aware chunks to preserve context
- Retrieval: Stores document embeddings in Qdrant and retrieves relevant content for each question
- Grounded answers: Generates responses using retrieved document context rather than relying only on general knowledge
- Citations: Includes the relevant document page number with responses
