Should I Offer Tech Freelancing Services Under My Startup?

I know it's officially meant for automation per articles of incorporation, but my dad is retiring soon and I can't really find a "proper" job (full time, permanent, standard hours, decent pay, good co-workers, etc). However, there's nothing legally prohibiting me from engaging in other business as long as it's related to tech, with the exception of game development for some reason. Because if I'm gonna advertise myself and offer tech services via NextDoor and other apps, might as well protect myself legally and give myself more credibility while I'm at it.
