About me

A bit about
who I am

I am a Software Engineering student at COMSATS University (CGPA 3.68/4.0) with a strong specialization in Artificial Intelligence, Machine Learning, and Natural Language Processing. My core expertise lies in architecting production-style RAG pipelines, fine-tuned hybrid retrieval algorithms (ChromaDB + BM25 with dense-sparse reranking), and autonomous stateful agents.

I build production-style AI systems that solve complex information retrieval, semantic resume matching, and workflow automation challenges. Combining robust Software Engineering principles with cutting-edge ML research, my solutions prioritize strict accuracy, zero hallucination, low latency, and clean backend architecture.

Sabaq — Class 11 CS RAG Assistant

A high-precision Retrieval-Augmented Generation system engineered to answer Class 11 Computer Science queries strictly from official textbook content across English, Urdu, and Roman Urdu. Features hybrid retrieval pairing dense ChromaDB vector search with sparse BM25 keyword matching via dense-sparse fusion, Gemini-based passage reranking, an automated MCQ generator, page/chapter lookup, a zero-hallucination syllabus guard rail, and a dedicated diagram/figure retrieval subsystem. Deployed with FastAPI and Next.js.

Resume Insight Engine

A semantic candidate screening platform that automates resume evaluation against complex job descriptions. Extracts unstructured PDF content, computes granular per-section similarity scores across Skills, Experience, Projects, Education, and Certifications using sentence-transformers, and applies KeyBERT/spaCy keyword extraction to quantify matched vs. missing skills with interactive Plotly visual analytics and downloadable PDF evaluation reports.

CareerPilot — Job Search Agent

An autonomous, human-in-the-loop job application agent built with LangGraph and Llama 3.3 70B (via Groq). Automatically conducts targeted job posting searches via Tavily, drafts customized application emails grounded in the user's verified background, accepts natural language revision commands, and executes Gmail delivery only after explicit human confirmation. Session state is persisted in PostgreSQL with automated logging to Google Sheets.
