Hello.
Welcome to my website.

I'm Beomjoon Ko. I build software, sweat the small details, and write about what I learn along the way.

I like simple tools, honest engineering, and building things that keep getting better after they ship.

Building products.

I take ideas from a rough sketch to something people use every day, and I care about everything in between: the edge cases, the loading states, the last pixel.

Learning continuously.

Every project leaves something behind. I keep notes, revisit old decisions, and fold what I learn back into the next thing I build.

Writing it down.

Writing is how I think. I publish notes on engineering, tools, and the occasional experiment that didn't work out.

Writing.

    All writing

    Experience.

    • Acme Labs - Software Engineer2025 - now

      Building the core product end to end, from API design to the small interface details people notice.

    • Northwind - Engineering Intern2024

      Worked on internal developer tools and made the test suite fast enough that people stopped skipping it.

    • Example University - B.S. Computer Science2020 - 2024

      Studied systems and architecture. Spent many late nights with assembly and enjoyed most of them.

    Bookshelf.

    Books I keep coming back to.

    Let's build something together.
