About Me

I build full-stack products and AI agent systems with React, TypeScript, Java, Spring Boot, PostgreSQL, and LangGraph.

Professional Background

I am a software engineering master's student at Northeastern University focused on full-stack development and AI-powered applications. My work combines React and TypeScript frontends, Java and Spring Boot services, PostgreSQL-backed data systems, and AI workflows using LangGraph, RAG, and LLM APIs.

I am currently seeking 2027 New Grad full-time software engineering opportunities, especially in full-stack engineering, backend systems, AI application development, and platform/product engineering.

Beyond the Code

Outside of software development, I am passionate about soccer and music. As the captain of my university soccer team, I led the squad to a championship title and was honored with the Golden Boot award. That experience shaped how I approach teamwork, ownership, and communication.
