Hi there, my name is Jiarui (it pronouces as "Jah-Ray", with the "J" as in "jam", and "Ray" like the English name). Welcome to my github page!

I am a ML Engineer / Quant Developer lead at a Bulge Bracket bank, where I led a team of engineers to develop intenral frameowrks for model development, implementation and deployment. We also build internal analytical tools to support variaous areas of the business.

I have also worked as a Data Scientist in a FinTech company before, where I have built the end-to-end machine learning systems for credit decision models.

I am actively involved in different AI/ML communities in London.

I am organising London Meetup. You can submit your talk at this link.

I am also volunteering at the annual London Conference.

I am also part of these communities:

• China-Britain Artificial Intelligence Association (CBAIA)
• Warwick Finance Professional Network (WFPN)

I write things in

• My LinkedIn Post, for short ideas/notes.
• My personal website, for longer blogs.

From various envents from PyData and NumFocus, I am deeply attracted by and involved in the open source community and making my initial steps to contribute to them. Check my github contributions in this page. 😄

Back in 2016, I finished my PhD in Mathsmatics at Warwick University. My supervisor were Stefan Grosskinsky and Paul Chleboun.

My reaserch was in the area of complex systems. Where I have investigated certain types of interacting particle systems. You can find my thesis here.

I also have a master in Financial Maths and an undergraduate in statistics. So, I was pretty much trained as a mathematician.
