While the technomancer may seem like the right way to 'magically' make robots and stuff the system mechanics actually go a different way in starfinder, making us of 'sufficiently advanced' technology as to be indistinguishable from magic.

The Mechanic and its accompanying drone are indeed the closest functional analog to the Summoner, or Druid with animal companion, to be found in the Starfinder setting. In addition to being an impressively versatile class it packs a real option for powerful abilities both in combat and outside combat in which crafting can be done easily.

I assumed you picked android because you like the theme, or the spacewalk option both of which are perfectly good reasons to go that direction.

Drop strength to 11 and raise Int to 16 because your skills really are the point of the class.

If you want a purely optimized character you want halfling for the stealth skill perks.

The laser pistol's range is indeed better, and the silent fighting style, as well as easier ammo recovery.

The theoretical loss of 1 point of average damage is laregely menaingless when compared to the damage from trick attack for both the laser and your knife.

I like Themeless for operative because it allows you to have just about every skill in the game as a class skill because they start with most anyways.

If you are looking for a real 'combat caster' rigged for functional melee combat give this one a look. It is based off your sheet but better in every regard assuming you don't need hair.
