I build systematic, rules-based trading systems in Pine Script.
Custom indicators, multi-signal confluence engines, alerting frameworks, and backtesting/robustness tooling — for traders, educators, and teams who need something built properly rather than assembled from templates.
What I build
Trend identification and classification, oscillators, momentum tools, and threshold-crossing logic — built to your specification.
Medium-term systems that classify the prevailing trend on an underlying asset, as a rules-based reading rather than a prediction. Crypto assets by background, but built for any asset class you're trading.
Expands on trend-filter methodology to examine relative strength across a basket of assets, ranking which are currently dominant — a descriptive reading, not a recommendation.
Every system ships with a report: walk-forward validation, parameter-sensitivity checks, overfitting diagnostics, and a plain-language logic summary.
Already have a strategy built? I can run the same robustness and overfitting checks on it as a standalone service, regardless of who built it.

Recent work
BTC Trend Filter — Consensus Score
A 7-signal consensus system (VIDYA, CUSUM, Vortex, Ribbon Concordance, TSI, Fisher Transform, Mann-Kendall) reporting a single vote count against a fixed threshold. Descriptive only — no position, asset, or action is labelled, and the reading only updates on confirmed bar close.
Fisher Transform Turning Points
A Fisher Transform-based state indicator distinguishing a live (intrabar) reading from the confirmed state at close, with a separate momentum-contraction/expansion read and a streak counter. Reads only the confirmed bar state.
Ribbon Concordance
Measures how consistently a moving-average ribbon is stacked, rather than relying on a single crossover — a rank-concordance score classified into four bands (Strong/Weak Bullish, Strong/Weak Bearish). Bands are confirmed at bar close only.
