See below for a guide/build on how to play Achilles in the jungle effectively. I'm currently trying to knock out the 40 or so jungle gods right now, so I'll be looping back and adding more to these whenever possible.
Start with armor off, you're gonna stay shirtless most of the game because of the additional scaling and stats. Alternatively you can go Bumba's Cudgel, or any of the other curios, as those are mostly preference. You skip leveling your ult as it does nothing but give you more damage on it, when ideally it should be executing people regardless. Most games you will need to start with blink, but if they don't have a lot of threatening/scary CC (rare) then you can rush Blink instead.
Just a preference option for more CDR, especially if you want to swap Pendulum for something else.
Optional swap for when you need to chase and confirm or get out of a bad situation quickly.
Fat selfish item that gives you 70 prots on one side and 50 on the other. Very solid choice if you want to be able to just eat hits mid-late game, especially if the enemy backliners have a lot of flat pen.
