Season beef with red pepper, onion powder, adobo, garlic powder, sazon, soy sauce, chicken bouillon cube, oregano & olive oil. Cover & let marinade 1-2 days.
Heat a pot over medium heat with olive oil. Add beef & brown on each side. Once beef is browned on all sides, add 3-4 c water. (I recommend putting water into marinade bowl so you don't waste marinade).You want water to cover beef. Cover pot & let beef boil 1- 1 1/2 hrs until beef is tender. Check on it occasionally, if water dries up, add more water. Once beef is tender, cut potatoes, carrots & onion.
Add regular potatoes & carrots. Stir, add more water if needed. Let beef & potatoes simmer for 10 minutes. Then add sweet potatoes & onions, stir. After 6 minutes, add red pepper flakes, stir again. Let boil 5 minutes.
Add tomato paste & brown sugar, stir again. Let stew boil until reaching desired thickness. Serve over white rice or with bread.
