WolLu (Jaeyun Jung) — Game Developer
</AboutMe>
Hello, my name is Jaeyun Jung, and I go by WolLu. I am a student developer who enjoys bringing ideas to life through games.
My interest in game development began in 2022 while studying cybersecurity and programming. During that time, I worked as a reverse engineer in the white-hat hacking team H4C, where I built a strong foundation in computer science, including low-level system knowledge.
Building on this foundation, I began turning ideas into fully playable game experiences.
I started out developing fan games for Korean streamers, and I currently work at the indie game studio AlephStudio and the HCI Lab at Daegu University.
