Project Details
I've documented the problem, approach, experiments, and outcomes here in an organized manner.
When building this project, my goal was to create a system capable of real-time monitoring of Telegram chats for specific keywords and triggering automated actions upon detection. The bot listens to messages using the Telegram Bot API, scans user messages, and executes predefined actions for matching keywords.
The project:
- ▹ Monitors specified keywords.
- ▹ Triggers functions associated with each match.
- ▹ Can send responses back to Telegram or trigger a webhook.
Installation and usage instructions are detailed in the README.
Project Story and Challenges
The main challenge I faced in this project was building an architecture that could monitor Telegram messages in real time and efficiently filter for keyword matches. As messages flowed continuously, I had to carefully structure the bot to ensure accurate scanning and filtering. Additionally, I optimized command/action mappings to keep the response logic flexible for various matched keywords.
Maintaining performance under repeated matches across different chats required efficient listening loops. This process gave me valuable experience with bot interactions, Telegram API rate limits, and real-time data stream management.
