Side Projects in C++ for HFT

Hi so I am currently working on embedded software. I have mostly done C, C++, C#, and Python.


I am planning to apply to HFT roles next year, and I wanted to know what type of side projects would be good for me to do so I can try landing a job in the HFT field?


Thank you!
