Everything from a rigor-first ML pipeline for market anomalies to an event-driven robotics architecture, plus a few smaller things built along the way.
Unsupervised anomaly detection over 14 years of B3 equities with an LSTM-autoencoder, built so the methodology actually holds up.
Every decision is a logged ADR (18 of them, including ideas rejected with proof — Transformers, Optuna, weight decay), guarded by 32 tests and walk-forward validation against temporal leakage.
An autonomous-robot MVP built on a clean observer-pattern core, so vision, control, and results stay decoupled.
Signals are typed — Frame, Control, Result — so each subsystem reacts to events without knowing about the others. Architecture as the feature.
