Heat half tablespoon of vegetable oil in a large skillet or wok over medium high heat. Add shrimp and cook until pink, stirring occasionally, about 2 to 3 minutes. Set aside.
Add remaining half tablespoon of vegetable oil and cook garlic and ginger until fragrant, about 1 minute. Add mushrooms, snap peas, water chestnuts, and baby corn, and cook until vegetables are tender, stirring frequently, about 4 to 5 minutes.
In a small bowl, whisk together soy sauce, chicken broth, sesame oil, sriracha, brown sugar, and cornstarch.
Add cooked shrimp and soy sauce mixture to the skillet and cook until the sauce is bubbling and slightly thickened. Garnish with sesame seeds and serve immediately.
