How to find hackathons in Bengaluru?

Hey Folks, I'm a software engineer with around 2yoe. My goal for this year is to get very good at tech (frontend and Backend). Currently I'm a Frontend Engineer working with React.

I've selected Golang for the backend in order to create software.

I want to start participating by the end of this year and next in many hackathons. I tried searching on Google but there are a lot of fake sites giving 0 information regarding this.

How do I find where hackathons are happening in and around the city?
