AI Agent Library
Project Overview
I developed a modular AI tool library that enabled rapid creation and orchestration of intelligent workflows. Built with LangChain for LLM-powered reasoning and LangGraph for visual graph-based orchestration, the library let developers combine multiple tools, APIs, databases, and custom functions into reusable "agent" pipelines.
In addition to the core framework, the library included prebuilt agents for web crawling and research, lead generation, marketing outreach, and customer service automation. Each agent could be customized or extended, making it easy to create new AI-driven workflows without starting from scratch.
This project showcased my ability to design scalable AI agent frameworks that blended large language models with structured workflows, giving teams a plug-and-play way to add advanced automation into their products.
The Challenge
Building AI agents from scratch is time-consuming and requires deep knowledge of LLM orchestration, tool integration, and workflow management. Most developers need to reinvent the wheel for each new automation task, leading to duplicated effort and inconsistent implementations.
The Solution
Created a modular library with reusable components and pre-built agents that developers can customize and extend. The framework handles the complexity of LLM orchestration, tool chaining, and state management, allowing users to focus on their specific use case rather than infrastructure.

Key Learnings
This project deepened my understanding of AI agent architecture and the importance of modular design in complex systems. I learned how to balance flexibility with ease of use, creating abstractions that hide complexity without limiting functionality.
Working with LangChain and LangGraph taught me valuable lessons about state management in AI workflows and the challenges of making LLM behavior predictable and reliable. The experience also improved my skills in API design and developer experience optimization.
