I also used Docker and Travis CI to deploy and host the bot on Heroku. And lastly, I used Datastore on Google Cloud Platform to store the bot usage statistics.</p> <h2> Additional Thoughts / Feelings / Stories </h2> <p>This was an interesting project as I have been receiving feedback from users to either fix bugs or implement new features. The bot has over 10,000 users and has processed over 65,000 tasks. Last year, one of the users also offered to help translate the bot into Italian. With the help of the users, the bot now supports 11 languages.</p> octograd2020
