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:
Extending the SimpleDRM graphics driver to parse the physical dimensions of displays and accurately calculate the DPI value for scaling
Implementing support for Windows Phone devices using the Qualcomm MSM8x26 family of SoCs, such as the Nokia Lumia 735 and the Microsoft Lumia 640 across a series of commits, alongside other people under the Mainline4Lumia project
Adding device-tree nodes for various components of the PM8226 PMIC used in Qualcomm’s MSM8226 System-on-Chip such as the PON (Power On) device, the VADC (Voltage ADC), the IADC (Current ADC) and the MPPs (Multi-Purpose Pins)
Adding driver support for the CCI (Camera Control Interface) on Qualcomm’s MSM8226 SoC, an I²C bus used to communicate with camera sensors, and nodes for the RPMCC and the MMCC (Multimedia Clock Controller)
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:
- Adding support for switching pipes between blocking and non-blocking mode on Windows - this also required modifying Python’s core read and write functions to handle error codes specific to Windows
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:
Before After 
Developing a new interface to view game information, which includes decoding the 5-bit bitmap and 16-bit palette, and repacking it into 32-bit ARGB
Image decoder C code Interface Added battery level emulation utilising low-level bit manipulation in C to configure the registers
