Not sure if Options trading for Income / Theta harvesting counts as Quantitative trading, but I found success here.

Long story short: I created an option backtester (MesoSim) and started analyzing public domain trades.

I have a couple of listed in this blog: https://blog.deltaray.io/tags/strategies/

If you are interested I'd suggest taking a look at the Weekend Effect, it's relatively easy to understand.

Best luck to you getting back to trading!
