Engineer Build - Any advice?

Hi, I took a long break from the game, but I'm back still as fun as ever.

I created a build using the Overclocks i have.

Overclocks

Voltaic SMG: EM Refire Booster, Well Oiled Machine

Breach Cutter: High Voltage Crossover

This is the link to the rest of the build. Would appreciate any advice.
