Проект был выполнен очень быстро и качественно. Более того, объем выполненной работы был выше, чем в ТЗ, так как в процессе сотрудничества с Дмитрием у меня появились некоторые идей, которые не входили в первоначальное ТЗ, и которые Дмитрий реализовал в полной мере и без никаких нареканий. Теперь сотрудничать в рамках Android разработки буду только с ним.
Рекомендую, однозначно.

Было очень приятно снова сотрудничать.
Код написан качественно, так же был постоянно на связи, сроки просто волшебные, большая часть работы была уже написана в день согласования ТЗ. Все правки вносил очень быстро.

Крайне рекомендую сотрудничать с Дмитрием, вы не пожалеете!
