Разработка сайта-портала провайдеров
Personal 1320 USD
Проект разрабатывался на протяжении года и он оказался достаточно трудоемким. Был момент когда возникло ощущение, что не закончим. Двигался проект медлено. Но ребята собрались в итоге, курировать проект начал Игорь Майданюк и дело пошло.
Отмечу терпение и профессионализм данного специалиста, шаг за шагом все обнаруженные баги дорабатывались и сервис постепенно начинал работать, как надо.
За сроки объективно оценку снизил, тут есть над чем работать, ибо время это деньги.
Качество работы меня в целом устраивает, но хотелось бы чтобы вы больше уделяли время тестированию, перед передачей результата заказчику.
Остальное 10 из 10
Думаю мы продолжим сотрудничество в будущем.
