Pat the raw shrimp dry with paper towels and pulse in a food processor until coarsely chopped, ensuring it does not turn into a smooth paste.
In a medium mixing bowl, combine the chopped shrimp, egg, almond flour, finely diced red bell pepper, sliced scallions, sea salt, black pepper, and garlic powder.
Stir the mixture until all ingredients are thoroughly combined and the binder is evenly distributed.
Form the mixture into four equal-sized patties, pressing them firmly so they hold their shape.
Heat the avocado oil in a large non-stick skillet over medium-high heat until shimmering.
Carefully place the patties in the skillet and sear for 3 to 4 minutes per side, or until they are golden brown and the shrimp is opaque and cooked through.
Remove from the pan and serve immediately while hot and crispy.
