In my free time I contribute to open-source projects on GitHub and work on various projects of my own. Here is a list of a few of my projects, check out my GitHub profile for more.

Graylog Plugin (Java)

TelegramAlert

Graylog is a feature-rich log management solution. What could possibly be missing? A Telegram Plugin of course!
Give this plugin a try if you're using Graylog and want a convenient way of receiving alerts.

Graylog + Telegram = TelegramAlert

SinusBot Scripts

Apart from being a moderator and administrator in the SinusBot Community Forum and Discord server, I also published a few scripts for the popular music bot:
Simple custom commands, AFK mover, Uptimerobot and more.

These scripts have been downloaded hundreds thousands of times already! The code is available on GitHub.
