What RL project can i do for my semester prohect

We have around 3.5 months to complete a project and i was looking for something that would help me understand RL as well as look good on my CV. I have already done projects on other AI domains and wanted to explore this one as well. I was thinking of using q learning for dynamic pricing based one two papers but im not too sure if theres a better project that im missing. Do u guys have any suggestions or pointers.
