I’m from Germany and looking for a part time job

Hello, My name is Hannes and I’m looking for a part time job in Seoul with a valid H-1 Working Holiday Visa, which means that I’m allowed to work 25 hours a week. My native language is German, but I’m also fluent on a near native level in English. I’m currently studying Korean, but my Korean is still on a beginner level. I’m open to almost every kind of job, that I’m allowed to do with my current visa.
