Boil pasta in water till tender, save 1 cup of pasta water for use later. Add some oil, salt, and fresh herbs to the boiling pasta. Drain and set aside when done.
While pasta is boiling, wash shrimp.
Melt butter over medium heat. Add shrimp.
Cook until the shrimp turns a little pink and starts to curl. Then add garlic.
Cook for 5-7 minutes, then add olive oil. Continue to stir until the shrimp is fully pink and curled.
Add pasta to the skillet. Add seasonings. Add just enough saved pasta water until the mixture is not dry but not swimming in liquid either. Depending on the amount of pasta, this requires 1/2 cup or all of it. Start with adding 1/4 cup, then work up from there.
Keep tossing all ingredients around in the skillet until everything is incorporated and hot.
