Soak the rice noodles in a large bowl covered with warm water for 25 minutes until they are flexible but still firm to the touch.
8 oz rice noodles
Heat 1 tablespoon oil in a wok or large skillet over medium heat. Add the beaten eggs and scramble them gently for 1-2 minutes until just set. Remove eggs to a plate and set aside.
2 eggs
Add another 1 tablespoon oil to the same pan and heat over medium-high. Add shrimp in a single layer and cook for 2-3 minutes, flipping once, until shrimp are opaque and pink. Remove shrimp to the plate with eggs.
1 lb shrimp
Drain the soaked noodles and add them to the hot pan with tamarind paste, fish sauce, and brown sugar. Toss constantly for about 2 minutes until noodles soften slightly and absorb the sauce.
