I'm a self-taught developer building MetaTrader 5 Expert Advisors, currently focused on NNFX-based systems. My main interest is testing discipline as much as strategy itself — in-sample vs. out-of-sample validation, ablation testing to catch overfitting before it matters, and production robustness (restart/recovery handling, error handling) that a backtest alone won't reveal.

Currently running two EAs on demo (EURUSD, and a separate CHFJPY/AUDCAD build with a regime filter), and working through a project log of around 18 tested variants — most rejected, a few adopted, all checked against unseen data before being trusted.

Also building a horse racing rating model as a separate project, applying similar testing discipline outside forex.
