PROFILE
Popov Alexandr
Over seven months, contributed to the musescore/MuseScore repository by building and optimizing core features in music notation software, focusing on audio processing, data handling, and engraving fidelity. Delivered enhancements such as a FluidSynth IIR low-pass filter for smoother playback, optimized path and instrument template searches for faster score operations, and improved engraving with explicit tuplet bracket visualization. Addressed bugs in file import, in-memory IO, and serialization, ensuring robust data parsing and accurate round-trips for 64-bit integers. Leveraged C++ and C, applying object-oriented programming, performance optimization, and digital signal processing to improve reliability, maintainability, and user experience across the codebase.
