McModder

Java, Kotlin/JVM full-cycle developer, DevOps

I build tools that solve concrete problems and don't require any voodoo to run. My main stack is Kotlin/JVM; for desktop I use Swing and Compose Desktop, and for automation and DevOps tooling I write CLI utilities and bots (Discord, Telegram). I set up servers from scratch with a single bash script (or an Ansible playbook), work with systemd, Docker, Nginx, and build CI/CD pipelines on GitHub and GitLab. I know how to ship my own app to production so that it lives there quietly and stays out of the way. What I deploy can run for months and years without trouble. I work as a freelancer and on my own projects - on the things I'd want to use myself.
