Custom MCP Server for Task Automation
Engineered and deployed a custom MCP server from scratch to empower non-technical users to execute complex data queries and automated tasks directly from their AI chat client.

Architected and built a modular, plugin-based backend using FastMCP (deployed with FastAPI on GCP), enabling to rapidly integrate new custom tools and capabilities with minimal overhead.
Developed the full-stack solution independently, from the server logic to the tool definitions, providing a seamless and powerful extension to the company's existing AI toolkit.
Automated internal workflows, such as database querying and information retrieval, to reduce manual effort and provide instant data access for team members.
Tech Stack: Python, FastAPI, Model Context Protocol (MCP), FastMCP, GCP

Modular Multi-Agent System with Human-in-the-Loop (HITL)
Designed and built a sophisticated, stateful orchestrator agent using LangGraph that dynamically routes user requests to a configurable suite of specialized sub-agents, handling everything from database interaction to external API calls.
Engineered a hierarchical architecture, personally developing the specialized sub-agents (e.g., SQL query, YouTube data retrieval) that were orchestrated by the primary agent.
Implemented a Human-in-the-Loop (HITL) workflow that pauses graph execution for user validation on ambiguous tasks (at the orchestrator level and subgraph level)
Integrated the complete agentic system with a Chainlit frontend to deliver an interactive chat application, managing the full communication pipeline from UI to backend.
Designed the system to be highly extensible, allowing new agentic capabilities (sub-graphs) to be added via simple configuration file changes, promoting rapid development and scalability.
Tech Stack: Python, LangGraph, LangChain, Chainlit
