Delivered a critical bug fix for TIFF compression presets in libtiff's tiffcp tool. The patch adds a switch to apply the preset compression level to lossless codecs (DEFLATE, LZMA, ZSTD), ensuring correct behavior and improving compression efficiency. This fixes incorrect application of preset compression levels, improving correctness and predictability for users relying on preset levels and contributing to storage efficiency. The change was implemented in libsdl-org/libtiff and committed as c2b7837a8c8a6f4879db13f442e5b28dcd9c3a2e (tiffcp: fix setting compression level for lossless codecs). Demonstrates proficiency in C/C++, compression algorithms, Git workflows, and code review.

July 2025: alisw/alidist — GCC 15+ build compatibility fix. Implemented a temporary patch to acinclude.m4 and the configure script to accommodate GCC 15+ and preserve build functionality, including updating the signature of GMP-related function 'g' to align with C23 changes. The change is documented in commit 350ba88149c3d0688a950c52dc7971a7304b8bb0 ("fix C23 compatibility in GMP (#5941)"). This work mitigates build failures with newer compilers, stabilizes packaging workflows, and demonstrates adaptability to evolving toolchains.
