Personal Details

• Preferred Name: Eric
• Legal Name: Yu Hu
• Email: eric@bktus.com (server in Germany)
• Headquarters: Germany

Note on Names: I’ve used the name Eric since childhood, and prefer it in nearly all non-Chinese contexts, especially online. My legal name, Yu Hu, is only truly accurate in Chinese characters and is rarely needed outside of legal or formal situations. It’s provided here mainly for code signing certificate verification. In formal settings, please use Mr. Hu.

About My Domain

The domain bktus.com (“Bakantu union us”) is just a personal domain I registered as a teenager. “Bakantu” is simply a made-up word—no hidden meaning! I just wanted a name that blended technology and community, reflecting values like innovation, connectivity, and collaboration. :)

Language Proficiency

I can use the following languages and welcome communication in any of them:

• English
• Chinese
• German
