Hi, I'm Tuan

I am a Full Stack Developer

 

Introduction

Overview.

Full-Stack Developer with 3+ years of hands-on experience building and deploying web applications. Proficient in React, Next.js, Node.js, and modern DevOps tooling. I bring a strong systems-thinking mindset — whether designing scalable architectures, automating crypto/Web3 workflows, or shipping clean, user-friendly interfaces. I work efficiently with AI tools like ChatGPT and Claude to accelerate problem-solving and stay focused on what matters.
