When your starter has doubled in volume (approximately 12-14 hours after mixing), mix your dough.
In the bowl of a stand mixer fitted with the paddle attachment, combine whole wheat flour, salt, olive oil, water and the fed and bubbly levain. Mix on low with the paddle attachment until the ingredients are incorporated. Remove the paddle and replace with the hook attachment.
With the hook attachment mix on low until a cohesive dough forms, approximately 1-2 minutes. Increase the speed to medium-high to develop. This will take about 10 minutes. It will pull away from the sides of the bowl, make a dough around the hook and not stick to the sides. The dough will look smoother than it did during before developing.
Lightly oil a bowl with vegetable or olive oil, spreading it around the bowl with your hands. Using a bowl scraper, scrape the dough into the oiled bowl and cover the top of the bowl with plastic wrap. Let it rest 30 minutes in a warm place and perform a series of folds.
Series of Folds: A series of folds is actually 4 folds. Always fold the dough towards you, rotating the bowl between each fold rather than trying to contort your body. You will get a tighter fold and shape. Grab one side of the dough and pull it up slightly then fold it down over itself into the middle. Rotate the bowl 90 degrees and repeat 3 more times, rotating after each fold.
Let the dough rest 30 minutes more and repeat the series of folds. The dough should stand tall and hold its shape in the bowl. If your dough sinks immediately after this second set of folds, you should make a third set of folds after letting it sit 15 minutes.
