Jyn Spring 琴春 vxst

Hi, I'm Jyn Spring (Chunqing Shan) 👋 这里是琴春哦

Stay fortitude, Do good, Be excellence: 永远坚强，永远善良，永远卓越

Advanced algorithm and mathematics (Rk.27 in National Olympiad in Informatics 2012), PR/ML
High-performance computing, broke the world records of HPL and HPCG
Full stack development and full stack deployment

SMIME: smime_vxst.cer (It's not as secure as GPG, but at least the email provider can't read your mail. It's the preferred encryption method since I can access it on the go, and it's safe enough for most use cases)
- You can always send me an email at [email protected], signed with your SMIME certificate, to request my signed reply, which will establish a trust tunnel for the future. This process is very easy with iOS/Apple Mail.
GPG: F085D7C448667DEF (Fingerprint: F2A1 B804 3905 5888 0DFE BBA0 F085 D7C4 4866 7DEF)
- Since my GPG secret key only exists within hardware tokens, I'll need a computer to decrypt the message. You'll wait more time before a reply (once a week), but this method is literally unbreakable.
