A technical specialist is required to assemble the architecture and logic of an interactive bot. The project is a gamified product with a deep storyline (U.S. market). What needs to be done: Transfer the finished script (dialogue tree) into the working logic of the bot. Set up strict timings, delayed messages, and conditions (if/else) depending on user actions. Implement the ability to integrate audio files and call external APIs. Platform: to be discussed. Suggest the optimal builder (ManyChat, SendPulse, etc.) or a custom solution if it is more feasible. Important: Your task is specifically the engineering assembly of the script into a functioning, fail-proof mechanism. The complete script will be provided to the selected specialist. In your response, please include: 1. Describe your experience in assembling bots with complex branching (autoresponders, gamification). 2. Which platform would you recommend for the bot, where messages must arrive strictly on a timer the next day (considering time zones), and why? 3. Provide your cost for completing the project and estimated timelines.

Good afternoon. I need a keyword parser that outputs results through a Telegram bot. How it should work: Automatic search on 4 websites for keywords that change from time to time. Search queries are sent every few minutes. The words are uploaded in the form of a .txt file. The Telegram bot should have buttons: start bot, stop bot, download file (downloads a file with active keywords), upload file (uploads an edited file with new words). The bot should ignore previously found results, i.e., it should not indicate the same ad twice. The result comes to the bot in the form of a link with a photo, but just a link is sufficient. P.S. searching websites without API, VPS with 6TB and 50 IPs are already available. For detailed information, please contact me via private message.
