About Me
I'm a Software Engineer at CedarDB specializing in modern database systems and high-performance data processing. I recently completed my Master's in Computer Science with high distinction at the Technical University of Munich (TUM), which included an exchange semester at UIUC. My technical background spans C++ development, compiler technologies, and WebAssembly, with a strong focus on building efficient, low-level systems and runtimes.
