B.Tech in Computer Science and Engineering 📅 September 2023 – June 2027 📊 CGPA: 8.05 / 10

May 2025 – September 2025

• Developed a production-grade food delivery PWA using React, Supabase, and Node.js, featuring 15+ pages, 35+ reusable components, OTP authentication, and real-time order tracking.
• Built a secure Razorpay payment pipeline with JWT verification and SHA-256 tamper detection, supporting wallet, COD, and online payments across 8 order lifecycle states.
• Optimized the data access layer by authoring 15+ PostgreSQL RPC functions and implementing service-worker caching across 20+ tables, enabling offline-first functionality and reducing redundant network requests.

AI-powered travel planning assistant using LangChain and LangGraph

• Architected an LLM-powered smart chatbot in Python using LangChain and LangGraph, orchestrating a Supervisor agent to dynamically route requests to specialized AI sub-agents.
• Built a RAG (Retrieval-Augmented Generation) pipeline with ChromaDB, using text embeddings and NLP techniques to improve contextual retrieval and reduce hallucinations.
• Engineered strict input guardrails and a Human-in-the-Loop (HITL) workflow for prompt safety and controlled AI interactions.
• Integrated PostgreSQL for structured data management and maintained the project using Git/GitHub.
