Hi. Wanting to contribute, not sure where to start.

Hi.

I am a long time linux user figuring that it's time for me to contribute.

A little background, career wise I work primarily as a system administrator / integrator with more than 10 years experience in the field.
Before this I was working on naval ship systems (primarility Windows NT based and unix based systems) to manage sensors and PLCs for my previous company, 
now I do office work as an Head of IT department managing windows clients, servers and HyperV VMs as well as maintaining connections and security for 3 branches.

On my side projects, I used to actively work on android custom ROMS back in my college days, as well as one of the primary developer for intel modded graphics drivers back in the 2000s.

After several years of using linux, I now only use fedora exclusively for both home pc and office workstations. 
So I think it's time for me to start contributing to the open source community, one thing to take of the bucket list, but I don't know where to start. 
If you have suggestions on where my skills can be of use, I'm all ears. 
Note: I am in GMT +8 timezone.
