My Work

Linux kernel

At the heart of countless devices and servers, the  Linux kernel stands as a testament to collaborative open-source development. With over 20 commits, I have made notable contributions, including:

Linux booting on Lumia 535

Python implementation

As the gold standard implementation of the  Python programming language, written in the C language, CPython, provides a robust and reliable interpreter for usecases from small scripts to large-scale systems. I have contributed to the project by:

melonDS emulator

Renowned for its high-fidelity emulation and rich feature set, melonDS has emerged as the go-to emulator for the Nintendo DS. I am a member of the melonDS team, actively engaged on adding new features, reviewing pull requests and code from external collaborators and tracing issues. Some of my significant contributions are:

  • Porting it to macOS (both x86-64 and ARM64 architectures), including adding a workaround in assembly code for the Mach-O executable format used

  • Redesigning the interface for configuring input to make it elegant and easier to use using the Qt framework:
