A working portfolio tracker for virtual accounts and shared households. It records transactions, calculates holdings, valuation, P&L and time-weighted returns, and tracks allocation drift using live prices.

FastAPI handles the main product workflows. Rust handles quote ingestion and calculation-heavy work. The public API uses OpenAPI; services communicate over gRPC using protobuf.

Active experiment · Training · Creator · ML engineer

The pipeline uses a conditional U-Net to predict a pitch-shifted mel-spectrogram, then HiFi-GAN turns it back into audio. Demucs can separate vocals before processing.

The pipeline is implemented, but training and model comparisons are still in progress. The diagram shows the intended signal flow.
