Fill a pot with water and bring to a boil.

Add the shrimp and boil until cooked through, about 3 minutes; remove from the water and set aside.

When the shrimp has cooled, chop into bite-size pieces and place in a large bowl.

Add lemon juice, lime juice, cucumber, onion, and jalapeno to the bowl; toss to coat and refrigerate for about 1 hour.

Add tomato and cilantro to the shrimp mixture; toss to combine.
