Complete the development from scratch to the final product of the "кватэрнiк?" Telegram bot for simplified registration, ticket sales, and event coordination. In 2022, my friend and me founded a creative project that merges art, music, literature, and design through events hosted in unique locations, such as apartments. Within six months, we achieved significant growth: attracting more than 680 participants and involving over 200 event authors and co-authors. We organized raves, room concerts, and cultural events, thereby forming an active creative community. We also collaborated with organizers, authors, and potential investors to further amplify the project's impact.
