Personal projects

Anatoliy Ch.'s Telegram super-app

November 2023 — now

Launched a 24/7 audio chat in the Telegram channel, featuring a bot that plays a variety of radio stations which subscribers can switch between directly through dot_ch_bot. The bot automatically grants speaking permissions to subscribers, facilitating random interactions among users.
Continues to engage subscribers by dropping monetary rewards in comments under posts to drive interest and interaction with the content.
Implemented "Vasily's Game" within the bot, an anti-lottery game with high expected returns but designed to be nearly impossible to win, costing 0.1 TON to play.
Integrated a feature to convert listens from Anatoliy Ch.'s music on streaming platforms into TON checks through a link to another bot project called "Delo."
Features a dedicated section for my Minecraft server, including connection instructions, a link to the spawn map, chat and voice chat options, and a real-time list of online players.
Incorporated a missing persons search feature, allowing users to upload a photo and check if the person is in any wanted database.
Added a weather information service that provides weather updates based on user-submitted geolocations.
Created a unique feature that generates haikus in the Bashkir language, showcasing the bot's cultural and linguistic versatility.
Developed a proprietary file system within the bot to manage a hierarchical structure of folders, files, and buttons, making it easy to share sections via links. Important links are aliased like t.me/dot_ch_bot?start=bashkir_haiku.

Music Artist

May 2020 — now

Utilized Spotify tracks to create unique voice message experiences on Tinder, enhancing engagement and interactions.
Developed proficiency in manipulating music streaming services, generating $1400 in revenue (September 2020).

Loyalty program

November 2022 — November 2023

Developed a Telegram bot that automatically issued TON checks through the @wallet account to incentivize channel subscription and engagement.
The loyalty program rewarded subscribers with TON checks for maintaining subscription status over time. Engagement was further encouraged through a tiered system that doubled rewards daily during the first week, introducing subscribers to the channel content.
Randomly distributed monetary checks in comments to increase engagement and motivate followers to subscribe to the channel chat.
Implemented a referral system allowing existing members to earn 50% of the rewards claimed by their referrals, enhancing the viral spread of the program.
Introduced interactive queue posts within the channel where users could 'line up' by pressing a button and chat in comments, maintaining engagement through gamification elements. Long inactivity would remove a user from the queue, culminating in monetary rewards for those who stayed active.

The loyalty program successfully grew the channel's audience by 300%. It has been replaced by a super-app featuring a radio, and the old loyalty program is now open-sourced and available at github.
