Pat the shrimp dry with paper towels.
In a bowl, combine the shrimp, minced garlic, fresh lemon juice, and salt. Toss to coat and marinate for 20–30 minutes if time allows.
Heat a large skillet over medium-high heat until hot.
Add the olive oil and arrange the shrimp in a single layer.
Cook for about 1½–2 minutes until the bottoms begin to turn pink.
Flip the shrimp and cook another 20–30 seconds.
Stir frequently until the shrimp are fully cooked and the garlic becomes lightly golden.
Reduce the heat to low and add the butter.
Once the butter has partially melted, stir in the soy sauce.
Toss continuously until the butter and soy sauce combine into a glossy coating that evenly covers the shrimp.
Divide the cooked rice between serving bowls.
Spoon the garlic butter shrimp over the rice.
Garnish with chopped scallions and serve with fresh lemon wedges
