Welcome

Hi! I'm Chengyuan. I grew up in Shanghai and graduated from MIT with a BSc + MEng in Computer Science. I currently work at Citadel as a Quantitative Research Engineer in its Global Quantitative Strategies (GQS) business.

I am interested in computer systems, particularly software performance engineering. In simple terms: I enjoy making programs run faster!

I built this blog to record and share my adventures in computing. Many of the notes here are just for my reference, but I'd be delighted if you find them useful too!

More about me, my blog, and my résumé can be found in the About page.
