Bring a large pot of salted water to a rolling boil. Add the pasta and cook until just al dente, about 1 minute less than package directions. Drain, reserving about a cup of pasta water, and set aside.
While the pasta cooks, peel and devein the shrimp if not already done. Pat them dry and season lightly with salt and pepper.
Heat 2 tablespoons of olive oil in a large skillet over medium heat until shimmering and fragrant. Add the sliced bell peppers, zucchini, and halved cherry tomatoes. Sauté for about 3-4 minutes until the vegetables are bright, fragrant, and just starting to soften.

Push the vegetables to one side of the pan. Add the shrimp to the empty side and cook for 2-3 minutes per side until they turn pink, opaque, and slightly firm to the touch. Gently shake the pan to distribute heat evenly.
