SYS_BIO

Hi, my name is Lee Sung Hak, from Busan, South Korea. My English-speaking friends call me Brian, and my Japanese friends call me Haruki. In the developer community, you might know me as Sashimi. I'm a full-stack developer with over 7 years of experience crafting elegant web applications.

My journey into development started unexpectedly. In university, I was captivated by creative tools like Adobe Premiere, Final Cut, Logic, and Ableton Live. These tools made content creation intuitive and empowered creativity. But I became more fascinated by how these tools were made than how to use them. This curiosity led me to web frontend development—a field that's constantly evolving with new technologies and endless opportunities to create.

I've worked across diverse environments—from conservative development teams to international R&D labs, from agile startups to enterprise platforms. My strength isn't just in React or Vue.js, but in solving problems wherever they emerge: whether that's frontend architecture, data pipeline optimization, internationalization, or building CI/CD systems. I believe great developers are utility players who enhance team productivity across domains.

Inspired by the precision of Korean craftsmanship and the clean simplicity of sashimi preparation, I approach development with meticulous attention to detail. Every line of code is an opportunity to create something both beautiful and functional.

CORE_DIRECTIVES

precision

Like preparing sashimi, every cut in code must be precise. Clean, intentional, and purposeful. Quality over quantity, always.

problem solving

The best developers aren't defined by their tech stack, but by their ability to solve problems. From frontend to backend, data to infrastructure—I go where the problem leads.

team first

Software is a team sport. Great code means nothing without great communication, collaboration, and mutual respect. I've worked across cultures and languages because good teams transcend barriers.

continuous evolution

Technology never stands still, and neither should we. Stay curious, embrace new ideas, and always be learning. Today's innovation is tomorrow's foundation.
