I'm a software developer who uses mostly Haskell, Kotlin, Java, Rust and last but not least C and C++. For Android and Spring Boot development I use Kotlin and Java. Also, I know the basics of relational database systems like PostgreSQL, SQLite, MariaDB and MySQL such as SQL and database normalization. I like Prolog and I'd like to learn more of it and about it. I know the basics of Linux and Bash, too. I use it on servers (Debian, Ubuntu) and on my desktop (Fedora).
