Projects

• Full-Stack Learning Dashboard
  React.js, GSAP, HTML, CSS, Express.js, PostgreSQL, NumPy, Pandas, Matplotlib, Seaborn

  Created a React dashboard where students log study sessions and see progress charts, with GSAP-animated transitions. Stored data in PostgreSQL behind an Express.js REST API. Used Python (Pandas, NumPy) to analyse study patterns and Matplotlib and Seaborn to generate trend visuals.

• MCP Server Toolkit for Database Q&A
  Node.js, Express.js, PostgreSQL, MCP servers, LLMs

  Built an MCP server that lets an LLM client query a PostgreSQL database through safe, read-only tools. Added an Express.js API layer with input validation and clear error responses for tool calls. Let users ask questions in plain English and get answers backed by live data.

• AI Research Agent with LangGraph
  Python, LangGraph, LangChain, LLMs, Prompt Engineering

  Built a multi-step agent that plans a question, searches sources, drafts an answer and checks it before replying. Modelled the workflow as a LangGraph state graph with separate planner, researcher and reviewer nodes plus retry loops. Wrote and tested structured prompts to keep answers grounded and formatted consistently.
