PROFILE
Alex
Alejandro worked on the LMMS/lmms repository, delivering features and fixes that improved the reliability and usability of the music editor. Over six months, he enhanced the Piano Roll and pattern editor by refining undo history, correcting key mapping algorithms, and implementing UI gating to prevent user confusion in empty projects. He removed dead code to streamline maintainability and introduced workflow improvements such as auto-gluing MIDI notes and guided onboarding for new users. His work demonstrated strong skills in C++, Qt, and GUI development, with additional focus on internationalization and localization, resulting in a more accessible and robust user experience.
