| Project | What I worked on | Pull requests |
|---|---|---|
| Apache SeaTunnel | Fixed MySQL CDC snapshot splitting for tables with non-consecutive primary key IDs by switching to sampling-based chunking. Also worked on RocketMQ consumer offset lookup failures. | #12463 merged #12462, #12340 closed |
| Google qsim | Enabled simulations beyond 32 qubits on AMD GPUs through 3D grid folding and 64-bit indexing. Also migrated formatting from Black to Ruff and fixed a cibuildwheel config validation error. | #1016 merged #1012, #1095 closed |
| TensorFlow | Fixed a segfault in AudioSpectrogram for negative window and stride values. Changed tf.linalg.logdet to use LU decomposition so non-SPD matrices no longer return NaN. |
#108808, #112110 closed |
| Google ADK (Go) | Dropped internal artifact parts from live history replay. | #1765 open |
| Google LevelDB | Fixed silent data loss for blocks larger than 4 GiB. | #1367 open |
| sktime / skpro | Fixed integer-index handling in time series splitters. Proposed programmatic lookup for MTYPE and SCITYPE in skpro. | sktime #11390 open skpro #986 closed |
| Canonical cloud-init | Added controls for files injected by the ConfigDrive datasource. | #7155 open |
| Microsoft Agent Framework | Forwarded the x-agent-user-id header to the toolbox proxy so OAuth consent binds to the calling user. |
#8561 closed |
| Gemini CLI | Enabled Gemini 3.1 Pro for standard-tier subscribers. | #20206 closed |
