The work is mostly web applications and the APIs behind them. Often enough it's system programming, on Linux, where I write backend applications.
Which language depends on the problem. PHP and TypeScript most days, Go or Rust when something has to be small and fast. Whatever I can, I publish as open source, if it makes sense.
Security is more of a hobby, and I put the weight on the defensive side. I'd rather read logs than break into anything.
The profiles below are the ones I actually use. My handle isn't the same everywhere, and there are people with names close to mine, so if an account isn't on this list, it isn't me.
