In April 2026, delivered a robustness improvement to the QualityControl workflow by adding explicit handling for empty histograms. Empty histograms now trigger a quality result of 'Bad', preventing misclassification and improving reliability of quality assessments across the CI/CD pipeline. The fix was implemented in AliceO2Group/QualityControl and committed as 13cd77ffc9c97ff8886228af3b2a47e4a7f60487, with accompanying validation to ensure no regressions in non-empty cases. Overall impact: higher data integrity in QC outcomes, reduced manual triage, and smoother downstream decision-making.

March 2026: Key improvements to the CTP pipeline in QualityControl. Delivered robustness enhancements and histogram scaling improvements, leading to higher data quality and more reliable QC monitoring. Notable changes include: refactoring CTPRawDataReaderTask to use a specific inputs list for clearer, more accurate data processing; implementing adaptive histogram maximum logic when NotLHC exceeds YesLHC, with dedicated handling for synthetic run types. These changes were implemented in AliceO2Group/QualityControl and committed as 7ebbd9f661ab2c5c5f76992e92534fad2b66566a and cc66b719bae9b04e753ab88d9f6433a915bf5232. This work improves pipeline reliability, reduces risk of mis-scaling, and tightens validation for synthetic runs. Technologies demonstrated: C++, code refactoring, and data processing domain knowledge.

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.
