Hello, I’m Claudio Constantin Cojocaru, also known as ctntc or ReXase.

I’m a programmer who focuses on backend development. Other programming related things I like to explore are compilers, virtual machines, programming language design and implementation.

I have experience in software engineering with Java, C++ and Rust. Though you’ll also see me use C#, Kotlin, Go, TypeScript, Dart and rarely Swift, Scala and F#.

Despite having use C++ a lot, I tend to not use it for new projects, instead, I pick a memory safe language, and if a non-GC language is required, I will pick Rust always.

Personally, not a big fan of making UI, but I do like using Flutter when I absolutely have to.

My current stack usually includes:

  • ASP.NET MVC with Entity Framework
  • PostgreSQL or SQLite3
  • React with React Router or SvelteKit
  • TailwindCSS

I speak 3 languages: English, Spanish and Romanian.

When I’m not coding, I’m probably pumping iron at the gym or gaming my ass off.
