I see no problems with your backstory, so I'm going to nitpick your character sheet.
You are paying a significant amount of points to be human. You could be an ork, save 10 bps, gain +1 body and low-light vision, and otherwise keep your stats the same. You could also be a troll and pay 10 points for +2 body and +1 strength, +1 reach, thermographic vision, and dermal deposits over what you have.
Willpower 2 is not a hot idea. 3 is the lowest I'd go - it's +1 Stun monitor box, and it's what you use to defend against a lot of powers.
You misspelled "Design" a few times in your skills.
Dodge, Gymnastics, and Unarmed aren't all needed. Unarmed+Gymnastics will do you just fine; I'd drop dodge.
Getting a rating 3 medkit is silly. Cough up 300Y more for rating 6.
I am not in general a fan of either the Firearms group or the Close Combat group. The reason is that both of them essentially load you up with redundant ways of rolling Agility + Skill to hurt someone, and while all of them have some advantages and disadvantages, you're better off being good at 1 close combat skill (I suggest Unarmed) and 1-2 ranged combat skills (not Longarms) than being mehhh at a lot of them. Pistols only, Pistols + Automatics, Automatics only, Pistols + Heavy Weapons are all sensible choices. Pistols are weak and easy to hide. Automatics are very flexible and above average at everything. Heavy Weapons has machine guns, grenade launchers and "sniper rifles," but isn't concealable.
I would seriously rethink both Cybereyes and Cyberears. You can wear contacts and earbuds that do the same thing for a lot less money and none of your soul.
Datajacks are just fluff in 4e; you can have one if you want but it doesn't really do anything.
Implanting your commlink is similarly largely a fluff thing on a non-hacker.
I will QQ about your choice of weapons, but I suggest you figure out what types of weapons you want to use first.
In general, this character strikes me as a bit unfocused. You are ehhh at a very wide variety of abilities, and I'm not sure what you want to be good at.
