Engineering + research, not vibes.
| Area | Focus |
|---|---|
| Research / Modeling | Regime awareness (trend vs mean-reversion), indicator diagnostics, signal design with leakage awareness |
| Backtesting | Crypto pipelines (Binance), MAE/MFE, win-rate vs tail-risk, stop-loss sensitivity |
| Execution | Bot-driven workflow on Linux/VPS, Docker, reproducible runs |
| Risk / Process | Position sizing, failure-mode thinking, robustness over "perfect params" |
