Bring a large pot of salted water to a boil, add the fettuccine, and cook for 8 to 10 minutes until al dente, then drain and set aside.
While the pasta cooks, melt the butter in a large skillet over medium-high heat, add the shrimp, and cook for 2 minutes per side until pink and opaque, then remove and set aside.
Add the minced garlic to the same skillet and cook for 30 seconds until fragrant.
Pour in the heavy cream, bring to a gentle simmer for 2 minutes, then stir in the Parmesan cheese and black pepper until smooth and creamy.
Add the cooked pasta and shrimp to the sauce, toss for 1 minute until well coated, season with salt to taste, and serve immediately.
