Denis — a fantastic developer. Worked quickly, accurately, and with respect for every detail.
The project was unconventional, with elements of absurdity, philosophy, and light fluidity — and he not only handled it but also breathed life into it.
Always available, responds quickly, does not do things formally but with soul.

Received not just an APK, but a foundation for a ritual that will one day change the world's digital hygiene.

Highly recommended. Maximum respect to Denis.

P.S. He "may make mistakes"? We all can. But this Denis is not one of those.
