Hello! Here’s a project Oki has been ambitiously preparing: “Developers Oki Met” — O.M.G. (오.만.개)!

From now on, Oki will meet a wide range of developers, listen to their stories about development, services, and their engineering philosophy, and share them with you.

Please support us until the O.M.G. series becomes “fifty thousand episodes”!

And if you’d like to appear on O.M.G. yourself, leave a comment or contact us at info@okky.kr.

In this episode, we invited Jeongmin Oh, the young CEO of DevFive, and unpacked everything about their open-source projects.

From his five-year startup journey to the hardships of learning Rust, marketing 고민, and future vision — he shared it all candidly.

If you’re interested in CSS-in-JS or braille technology, this is a must-watch!

Key Topics

· DevUp UI: A zero-runtime UI library that completely solves CSS-in-JS runtime issues with Rust!

Started this January, surpassed 281 GitHub stars, selected as a speaker at FE Conference, and even being reviewed by Toss…

It’s emerging as an alternative for developers tired of Tailwind’s long class names.

Includes behind-the-scenes development stories, wild bug tales (on the level of Adblocker-style surprises), and open-source business strategy insights!

· Braillify: The only open-source library that follows the 2024 revised Korean braille standard.

Currently being developed based on the visually impaired editor “Touching Memory.”

Covers the reality of a braille industry that has lagged behind for 20 years, and the developer mindset of “I do it because I can.”

About 70% of Korean implemented so far, with plans to expand to English, math, and music braille as well!
