About Me

Who, me? You can call me John if you want, or you can call me jagrosh. I like making things, especially things that help or entertain others. I have a Bachelor's degree in Computer Science. I spend my free time writing software, singing, making code more efficient or succinct, and occasionally playing video games.

Open-Source Libraries

I like making things. I also like making useful things for other people to use.


JagTag is a simple (yet powerful and expandable) text-processing language. JagTag started as a (hard-coded) set of text replacements for a chat bot, but continued to expand until I decided to remake the entire thing as a standalone library. JagTag is used within some fairly-popular Discord bots such as Spectra, Yggdrasil, and Laxus.



After writing the same code repeatedly to work with databases (and hating the lack of typing in String-based SQL statements), I wanted to make something that acted as a very thin layer between the developer and JDBC to allow the developer to use typed variables and methods while still boiling down to SQL statements internally.



This is a library to communicate with the Discord client in order to utilize Discord's Rich Presence.



JDA-Utilities is a series of tools and utilities for use with JDA (Java Discord API) to assist in bot creation.

Discord Bots

One of my favorite hobbies is creating various bots (and other things) for the online chat service Discord.


A multi-purpose, for-fun and for-utility Discord bot. Spectra has a complex tag system for a plethora of "custom command" capabilities. Additionally, it sports utilities like reminders, announcements, self-assignable roles, afk notifications, and a full moderation suite including logs.



A moderation and auto-moderation bot with a suite of tools to protect servers from spam and advertisement. Its auto-moderator capabilities also allow it to filter out certain types of behavior without need for human intervention, lightening the load on the server's staff team.
