Bring a medium pot of water to a boil and poach the shrimp for 2 to 3 minutes until they are pink and opaque.
Drain the shrimp and immediately submerge them in an ice bath to stop the cooking process and ensure they remain tender.
Once cooled, pat the shrimp dry and chop them into bite-sized pieces, then place them in a large glass mixing bowl.
Pour the fresh lime juice over the shrimp and let it marinate in the refrigerator for 15 minutes.
While the shrimp marinates, dice the cucumber, tomato, and red onion, and finely mince the jalapeño.
Add the diced vegetables and chopped cilantro to the shrimp bowl.
Gently fold in the diced avocado, olive oil, chili flakes, sea salt, and black pepper until everything is evenly coated.
Serve immediately in a chilled bowl or over a bed of leafy greens for extra volume.
