About Me
I'm a master's student @TUM studying Informatics and a software engineer with over 5 years of professional experience in web- and backend development. I specialize in the building of high performance compilers and runtime systems for programming languages. Currently focused on high speed execution of WebAssembly and an alternative Django webserver runtime.
