Music Blocks Performance

Working on a measurement-first performance framework for Music Blocks v3 (Sugar Labs) , a browser-based visual music programming tool used by students and educators worldwide. Focused on eliminating UI freezes during LilyPond export, MIDI import, and complex block graph execution by introducing progress feedback, cancellation support, a frame-budget execution scheduler, and Web Worker offloading. Building runtime instrumentation using the Performance Observer API and integrating automated CI benchmarks via GitHub Actions to prevent regressions.
