Projects

Agentic RAG Chatbot

Built a multi‑agent Retrieval‑Augmented Generation (RAG) system integrating LLMs with specialized reasoning chains. Implemented embedding pipelines and vector search (FAISS) for context‑grounded responses, reducing hallucinations by ~30%. Designed modular agent architecture using Hugging Face Transformers for orchestration and reasoning workflows. Packaged as a Dockerized Flask API with CI/CD (GitHub Actions) and AWS deployment; developed custom prompt engineering strategies, routing logic, and tool‑calling capabilities.

AI Meeting Assistant

Engineered an end‑to‑end meeting intelligence platform with audio capture, transcription, summarization, and actionable insights. Leveraged OpenAI Whisper for transcription and GPT‑4 for multi‑view summarization (action items, decisions, agendas). Created multi‑agent processing pipelines with specialized prompt modules for meeting analytics and Jira integration. Built group‑based knowledge organization with persistent context storage for personalized summaries and automated distribution of structured notes.

URI Senior Capstone Project

Robotic Assembly, Inspection & Test Automation — developed an automated assembly workstation using robotics and visual inspection to enhance PCBA production efficiency. Designed control software to manage robots, conveyors, and sensors, generating production data and reports. Integrated multiple automated assembly subsystems to deliver a cost‑effective, adaptable solution, and modeled physical systems in Fusion 360 with 3D‑printed components for precise integration.

Automated Water Mister

Developed a fully integrated water mister system tailored for maintaining optimal conditions for my pet gecko. Utilized embedded systems with advanced BLE chips alongside temperature, humidity, and water level sensors to ensure precise environmental monitoring. Designed custom circuits interfaced with an Arduino and integrated graphics via I2C communication for real-time system feedback. Additionally, employed Fusion 360 for detailed CAD design and 3D printing of components, resulting in a cohesive, adaptable all-in-one mister unit.
