hello world!

about me.

I'm a developer heavily focused on backend systems, cloud infrastructure, and Linux. I find joy in building tools that act as the invisible backbone to things we use every day.

I'm constantly pushing code to open source in my free time. When I'm away from the terminal, I'm probably experimenting with a new language or fine-tuning my Neovim config.

Let's build reliable software together.
