I created a Telegram bot for monitoring cryptocurrencies on various cryptocurrency monitoring services. I created the bot's telegram using the Telegraf library. After that, I deployed it on Heroku. I developed a system for personnel accounting (departments).

 I developed it using the express framework and stored the data in two databases, MySQL and MongoDB. To work with MySQL, I used the sequelize ORM, and for MongoDB I used the mongoose ODM.
I plan to start working with typescript on the Nest.js framework.
