In a medium bowl, combine the soy sauce, brown sugar, oil, ginger, garlic and red pepper flakes. Add the shrimp; mix well. Place in the refrigerator to marinate for 30 minutes.
Coat a nonstick medium saute pan with cooking spray; heat to medium-high heat. Once hot, add the shrimp and saute for about 1 minute. Add half of the marinade mixture to the pan and cook for another 30 seconds. Discard any leftover marinade.
