Обо мне
Правильно работающий код, радующий пользователей и приносящий бизнесу прибыль - лучший код. После того, разумеется, который так и не был написан.
Решаю задачи лучшим подходящим для ситуации способом: никакого перфекционизма - только золотые середины.
Не держу справочные знания в голове: всё, что может быть найдено в Гугле, - должно быть найдено в Гугле.
