Sungmin Lee

Software Engineer & Classical Guitarist

About Me

I'm a fullstack software engineer with over three years of experience building scalable, user-friendly web applications. I specialize in React, Next.js, Node, and TypeScript, and enjoy working across the entire stack — from crafting intuitive frontends to building robust serverless APIs on AWS and Azure.

Before diving into software development, I pursued a deep passion for music as a classical guitarist. I hold both a Bachelor's and a Master's degree in Classical Guitar Performance and have been honored with several awards and certifications along the way.

My background in music fuels my attention to detail and creativity, which I bring into every project. Over the years, I've honed my skills with technologies like React/Redux, Express, Flask, Sequelize, and SQLAlchemy, always eager to learn and solve challenging problems.

I've worked in fast-paced startup environments where I led architecture discussions, developed modular UI components, and built secure, scalable backend services. I thrive collaborating with cross-functional teams and delivering polished products that users love.
