Resumé

about

🚀 Who is Harry Park?

I’m a software engineer with practical experience delivering end-to-end solutions—from system design to deployment—through both an industry internship and personal projects. I enjoy turning product ideas into scalable software using technologies like React, Next.js, NestJS, PostgreSQL, and Spring Boot. With a strong foundation in computer science and a passion for clean architecture, I thrive in engineering teams that value collaboration, performance, and thoughtful design.


🌱 Personal Note

Outside of code, I love designing scalable systems, exploring new frameworks, and creating minimal yet functional UIs. I’m also into clean architecture, thoughtful engineering—and acrylic painting when I need a creative reset.
