Okay, quick comments:

You've overslotted a lot of your toggles. Combat Jumping only costs 0.06 Endurance per second, so an EndRedux there is a waste of a slot. Similarly, you've slotted your toggles for heavy EndRedux, but left the resistance completely underenhanced. Super Jump should not be running in combat, so a single EndRedux is plenty. Lightning Reflexes shouldn't be slotted past the default - you'll get more bang for your buck slotting Sprint, and the real benefit or LR, 20% Recharge, is unenhanceable. Build Up's Endurance cost isn't what's causing your endurance problems - skipping Stamina is more likely the cause. Slotting Energize for Recharge will save you more endurance, through having that endurance discount up more of the time, than slotting for endurance reduction ever would.

Conversely, your attacks are underslotted. You don't have enough damage in your heavy hitters, especially Lightning Rod. That power demands three damage SOs or an IO frankenslotting.

You probably have too many attacks here. There's no way you could use even half of them before the rest had all recharged, so those powers are mostly sitting on your tray, unused. In particular, I'd reconsider Caltrops - it causes scatter because the mobs run in all directions, and with Elec Melee's heavy AoE focus, you want tightly-packed groups of enemies to lay waste to. The Stealth pool also sounds much better than it is. for the most part, a Scrapper can just kill anything between the two points you want to go, or at worst turn on your travel power and outrun the enemies.

Finally, Confront is widely considered fairly useless on a Scrapper of any description. If you want something's attention quickly, unload a Thunder Strike into its face - if you can't hold its attention through doing damage, either there's a Tanker you're fighting for aggro, which the Tanker will win, or there's a squishy doing something really stupid, like keeping Healing Aura on auto, and it is, regrettably, their own fault.

Anyway, that's my advice. The important thing is whether the character is fun for you to play. But with the amount of endurane slotting going on here, I'm suspicious that you're getting tired of hitting Rest every time it's up. There are plenty of guides around the forums for ways to avoid the No Endurance Blues, especially on Elec/Elec.
