Tommy De Jesus Rosario Santiago

I'm a specialized software developer focused on **algorithmic trading and financial automation**. I turn complex trading ideas into robust, reliable tools for **MetaTrader 5 (MQL5)** and **Python**.

My specialty is **prop-firm compliant Expert Advisors** — EAs that respect funded-account rules (daily & total drawdown limits, fixed-risk position sizing, automatic daily stop), so your bot becomes challenge-ready instead of breaking the rules. I also build custom indicators, desktop & web trading apps, and **Telegram-connected bots** for live alerts.

**Technical expertise:**
- **MetaTrader 5:** full EA development, custom indicators, on-chart HUDs, script automation.
- **Python:** trading bots with GUIs, web dashboards (Flask), MT5 API integration, Telegram bots, data analysis.
- **Strategy logic:** trend-following, breakout/ORB, mean-reversion, multi-timeframe analysis, ATR-based risk & recovery modules.
- **Risk & validation:** prop-firm rule engines, risk-% sizing, and **honest backtesting with walk-forward/forward validation** — I don't sell "guaranteed profits", I deliver solid engineering.

I value clear communication and technical excellence. My goal is to deliver dependable tools that let you trade your edge without emotion.
