Technology is one part of the victory. The other part is working with people, because you can’t take over the world alone (unless you are able to build an invincible battle robot, but first you need to get there). You need strategic skills, business skills, psychology skills, and cult-leadership skills, because you essentially face two types of risks—one is the risk that your technological and military strategy fails (just like when you would lose in a strategic computer game), other is the risk that generally everything will go successully, until in some unexpected moment someone you trusted (or just did not think too much about) stabs you in the back (either literally, or steals or sabotages your technology, incites revolt, etc.).
I guess it would be wise to surround yourself with a cult following, and spend extra energy on convincing those people about your supernatural powers (there need to be some extra secrets, beyond your technology and medicine skills that people see). Those people must be convinced that killing and replacing you would not be even in their short-term interest; otherwise someone will be tempted someday, and it only needs one assassin to kill you. You can always promise much more than you can really deliver… and so can your enemies. Even if you bring education, medicine, food and technology, someone can kill you in exchange for a hope of eternal happiness. Or they can be blackmailed.
I am not sure if it would be safer to stay hidden and surround yourself with brainwashed puppets (skilled enough to do their jobs) -- so when someone must go to the Roman court, or someone is assassinated, it’s them, not you. Basicly, for each skill you will exhibit (military strategy, technology, education, medicine, agriculture), select one or two persons already skilled in this area (leader, scientist, philosopher, healer, farmer), teach them, brainwash them, and let them pretend to the public it’s their skill. You can also appoint a false prophet for the public. You would delegate some tasks to some people anyway, with this strategy you just hide yourself from the attention of the outside world.
