Hey I'm better known to most people here as SFG. I make characters of varying quality sometimes, either for ai vs ai sites, or to see what is the limits of default mugen are like making a tetris ai, a raycaster engine (think original doom) or 100s of thousands of palettes, although nowadays I spend way more time helping other people make characters by answering any coding questions people have.
I'm not the kind of person to post a lot on forums, only where I feel like my input is valuable so you probably won't see me posting much, but I do tend to read everything, and will be active on the discord.
