Hello! I'm Dohui Ryu, a developer-entrepreneur working to build a better world through IT.
I write code to turn imagination into reality and give people the gift of possibility.
In 2023 I founded and now run HORANG EDU Corp..
What I’m building—
Right now I’m creating “Horang,” a service that teaches coding in Korean so children who struggle with English-based languages can learn to program with ease. My goal is a world where anyone can swiftly develop computational thinking and build the software they envision, while also giving teachers tools that remove everyday pain points.
What we’ve achieved so far—
- Completed multiple Korean government startup programs, including Youth Startup Academy, and raised investment from the Yoonmin Foundation.
- Researching and developing classroom-friendly features such as an AI Coding Tutor powered by RAG techniques.
- 45 + schools and learning centers already use Horang, both free and paid.
Other projects & recognition—
- Built “KOSMOS,” a service that mitigates crowd turbulence—the root cause of crush disasters like the Itaewon tragedy—and was selected for the Korean delegation to EUCYS 2023 (European Union Contest for Young Scientists).
- Ideated social-venture products such as “Seni(or)Bank,” a banking service for older adults, and “Kkotpang-i,” a digital education platform.
- Led campus projects including “DimiPay,” a facial-recognition cafeteria payment system, and “Dalgeurak,” a convenient meal-kit service.
- Honored with the 2022 Korea Talent Award🏅, presented by the Deputy Prime Minister of South Korea.
I’ll keep writing code that transforms imagination into reality—so more people can dream, build, and thrive.
In addition, I have experience in researching artificial intelligence and writing artificial intelligence papers on topics related to stock price prediction.
