Bring a stockpot of water to boil. Add 1 tsp of salt to water and cook thin spaghetti, according to package directions. Drain. While pasta is cooking, place shrimp in a small bowl and add the remaining 1/2 teaspoon of salt and the cornstarch. Mix well and let sit for 8 minutes. Rinse the shrimp well, washing off the salt and cornstarch. Pat very dry with paper towels.
In a wok or large skillet, heat cooking oil on high until a bead of water sizzles and evaporates upon contact. Add the shrimp and fry until halfway cooked through, about 1 minute each side. Dish out the shrimp to a plate, keeping as much oil in wok as possible (you should have about 1 teaspoon of oil left and you may add an just a bit of oil into the pan if needed.)
Turn heat down to medium and add garlic. Fry until fragrant, about 15 seconds then add the snow peas and carrots. Fry for 1 minute, until the carrots and snow peas are cooked but still retain a nice crunch. Add the soy sauce and rice wine. Turn heat to high and add the drained spaghetti noodles and shrimp. Toss well to combine. Let cook for 2 minutes, until shrimp is cooked through. Toss with sesame oil and sesame seeds.
