Worked on improving the font rendering pipeline in the fosskers/raylib-1 repository, focusing on resolving a bug related to composite glyph scaling within stb_truetype. Addressed issues with how scaling factors were applied to vertex coordinates, ensuring the transformation matrix remained stable during glyph scaling operations. This fix enhanced rendering fidelity and improved cross-platform consistency for scaled text, reducing visual artifacts and maintenance risks for downstream projects. Demonstrated strong debugging skills and a deep understanding of C programming, font rendering, and graphics libraries. The work contributed to more accurate and reliable font rendering in open source graphics applications using C.
