I build AI systems that go from idea to something people can actually use — agentic workflows, RAG pipelines, and ML models with real, measured performance numbers. Currently a CS (Data Science) undergrad, recently an AI Intern at DEAL, DRDO, working on agentic RAG pipelines for defence-relevant data retrieval.

• 🔭 Currently building: OpsCopilot — a LangGraph ReAct agent for business operations with human-in-the-loop approval
• 🌱 Exploring: multi-agent systems, LangGraph, computer vision, and production-grade LLM apps
• 💬 Ask me about: LangGraph, LangChain, RAG, ChromaDB, FAISS, YOLOv8, prompt engineering

Python · FastAPI · SQLAlchemy · LangGraph · LangChain · Pydantic · SQLite · Streamlit · Groq

A LangGraph ReAct agent (Qwen3-32b) with 12 tools spanning read ops (revenue, active users, expiring memberships, bookings) and write ops (extensions, phone updates, cancellations), gated by human-in-the-loop approval before any mutating action.

• ✅ 100% intent-to-tool accuracy across 12 test queries
• ✅ ~1.5s average response latency
• ✅ Approval-gated workflow correctly blocked/handled 80% of invalid inputs in edge-case testing

YOLOv8 · PyTorch · Python · Streamlit · OpenCV

Fine-tuned YOLOv8m to detect PPE items (helmet, vest, gloves, boots, goggles) and personnel on construction site imagery, paired with a geometric rule-based compliance engine.

• ✅ 0.80 mAP@0.5 overall (0.75–0.89 across individual classes)
• ✅ Diagnosed and resolved severe class imbalance in minority labels via per-class mAP analysis
• ✅ Interactive Streamlit app for real-time image/video compliance checking

Python · FastAPI · scikit-learn · LangGraph · ChromaDB · Sentence-Transformers · Groq · HuggingFace

LinearSVC multi-output ticket classifier feeding a LangGraph multi-agent RAG pipeline for automated, context-aware ticket routing.

• ✅ 97% accuracy / 96% F1-score across 10 departments & 3 priority levels, trained on 25,000+ tickets
• ✅ Deployed via FastAPI on HuggingFace Spaces
• ✅ RAG context retrieval via ChromaDB + Sentence-Transformers for domain-specific responses

🔗 GitHub

Python · LangChain · HuggingFace · FAISS · Groq LLM · Streamlit

RAG-based chatbot that ingests PDFs and ZIP codebases for semantic code search.

• ✅ Indexes 10,000+ chunks with sub-second retrieval via FAISS
• ✅ ~1.5s response time using Groq-powered inference
