All that the sensei quality does is give you an instructor for one skill group. It may be useful, but if the GM hand-waves character improvement with Karma, you will be throwing away points on this. Check with your GM.
From a quick look:
You can only have one 6 or two 5's for skills - not a 6 and a 5. I would consider getting the skill group for your stealth skills. You have redundant close combat skills, and the firearms group is too low. I would stick with a single melee skill for now, and break up the firearms group so that you can be good at one ranged skill. Ideally, an infiltration expert should have the hardware skill. If you are going to rely on a MagLock passkey, then it should be at rating: 4. You might want to add a rating: 6 autopicker in case you ever run into a more old-fashioned lock. Your biggest omission, augmentation-wise, is that you have nothing increasing Agility, which is your most important Attribute (indeed, you might consider lowering Willpower by 1 to soft-max it). I would get muscle toner: 2, or even muscle toner: 4 with the restricted gear quality.
