Building a psi character for a newbie

[Megabiquette]

Hello everyone!
For my second run I want to psi guy (I didn't take the red pill on my first one).
But I also want to build a hacker (my first one was a lockpick guy) AND an electronic crafter (my first one was good at all craft but electronic).

But there are 3 psi skills, and I don't know if I should focus on one or two or mix them. Also, should I also invest skill points in a back-up fighting skill in case I run out of psi? (I'm thinking about guns, to craft and use plasma pistols).

Thinking about all this, I feel like going the psi way eats a lot of skill point. Can you give me any advice on building and playing a psi guy? Thanks!

There are three builds on forum that hybridize psi with melee, one is fist fighter other uses maul and third abuses sniper rifles. You should check them out.

It is best to max out no more than 2 skills (because of feats - there are different for every skill and you wan't be able be master all of them). On my first playthrough I builded psi-melee char and used all three skills quite effectively.
