Angel is a creative individual with a deep passion for problem solving. He brings over two decades' burden of development and management extensive, methodical and honest quality assurance trolling, which have toughened him so much that he doesn't care about the correctness of stating: "Your baby is ugly." And he really does not care if it is ugly, he cares more about the steps to reproduce and maybe throw a couple of facelift suggestions along the way.

So the next time you see a sign saying “Beware of the troll,” keep calm and keep in mind it is not him, it's just his quality report. And sometimes Angel have gone wild and beyond by dabbling in UX, coaching Design Thinking, facilitating workshops, and even conducting Quality and Design Basics training, documenting just about everything along the way: plans, tests, bugs, mental disorders... (you have reached your 600 char limit).
